Creates a CalculatedProperty for a Group. Each CalculatedProperty defines a property or 'column' which is calculated for each element that is returned by the Group's query.

### Calculation Types

Calculation types that start with `BoundingBox` use element aligned bounding boxes. They can be used for approximations of geometric element dimensions when there are no available properties that would have exact dimensions. Some errors may occur due to bounding boxes not being a perfect fit for the surrounded element.

List of all available calculation types:

- `Length` - calculation of a linear element length or a perimeter of a geometric element that does not have a volume. For elements that have a volume use BoundingBox calculations to approximate the length.
- `Area` - calculation of a geometric element's surface area.
- `Volume` - calculation of a geometric element's volume.
- `BoundingBoxLongestEdgeLength` - calculation that gives the longest edge length of an element aligned bounding box.
- `BoundingBoxIntermediateEdgeLength` - calculation that gives the edge length that is not the longest nor the shortest of an element aligned bounding box.
- `BoundingBoxShortestEdgeLength` - calculation that gives the shortest edge length of an element aligned bounding box.
- `BoundingBoxDiagonalLength` - calculation that gives the distance between 2 opposite corners of the element aligned bounding box.
- `BoundingBoxLongestFaceDiagonalLength` - calculation that gives the longest distance between 2 opposite corners of a face on the element aligned bounding box.
- `BoundingBoxIntermediateFaceDiagonalLength` - calculation that gives the distance between 2 opposite corners of a face on the element aligned bounding box that is not the longest nor the shortest.
- `BoundingBoxShortestFaceDiagonalLength` - calculation that gives the shortest distance between 2 opposite corners of a face on the element aligned bounding box.

Creates a CustomCalculation for a Group. Each CustomCalculation defines a column in the output data which is filled with values calculated using the given formula for each element that is returned by the Group's query.

### CustomCalculations

CustomCalculation is a type of Group property which contains a formula. CustomCalculation defines a column in the output data that gets filled with the formula evaluation result. The formula is evaluated for each row of the Group's query result during each extraction.

The formula supports using other columns (GroupProperty, CalculatedProperty or CustomCalculation entities) as variables. Recursive formulas are not supported, i.e., formula containing a variable `X` is not supported inside a CustomCalculation with a `propertyName` equal to `X`.

Supported data types:

- Number - describes a real number. When converted to a boolean value in logical operators `0` becomes `false` and all other values become `true`
- Boolean - describes a logical value which is either true or false. When converted to a number in certain operators `true` becomes `1` and `false` becomes `0`
- String - describes text. When converted to a boolean value in logical operators an empty string becomes `false` and all other strings become `true`

All of the supported data types can have no value which means that the value is `null`. Some operations support `null` values but those which do not will return `null` as the result.

Supported operators:

| Symbol | Name | Precedence | Associativity | Operand Types | Can receive null | Result |
|--|--|--|--|--|--|--|
| Unary `-` | Unary negation | 9 | Right | Numbers and booleans | No | Number |
| `!` | Logical not | 9 | Right | All data types | No | Boolean |
| `**` | Exponentiation | 8 | Right | Numbers and booleans | No | Number |
| `*` | Multiplication | 7 | Left | Numbers and booleans | No | Number |
| `/` | Division | 7 | Left | Numbers and booleans | No | Number |
| `%` | Remainder | 7 | Left | Numbers and booleans | No | Number |
| `+` | Addition | 6 | Left | All data types | No | Number or string if one of the operands is a string |
| Binary `-` | Subtraction | 6 | Left | Numbers and booleans | No | Number |
| `<` | Less than | 5 | Left | All data types | No | Boolean |
| `<=` | Less than or equal | 5 | Left | All data types | No | Boolean |
| `>` | Greater than | 5 | Left | All data types | No | Boolean |
| `>=` | Greater than or equal | 5 | Left | All data types | No | Boolean |
| `==` | Equality | 4 | Left | All data types | Yes | Boolean |
| `!=` | Inequality | 4 | Left | All data types | Yes | Boolean |
| `&&` | Logical and | 3 | Left | All data types | No | Boolean |
| `\|\|` | Logical or | 2 | Left | All data types | No | Boolean |

Parenthesis `(` and `)` can be used to change the precedence of operations. Variables, constants, and functions have a precedence of 1 and left associativity.

Mappings created or modified by using the "Try it out" function can only extract a maximum of 100 rows for each group. Mapping modification is considered any POST/DELETE/PATCH/PUT request to any endpoint with the tag "Mappings" or if the URL contains {mappingId}.

---


create-customcalculation

Id of the Group for which to create a new CustomCalculation.

Created a new CustomCalculation successfully.

Specified CustomCalculation was not found.

CustomCalculation with the same name already exists within the Group.

Creates a Group for an iModel data source Mapping. A Group is a collection of design elements from an iModel represented by an [ECSQL](https://www.itwinjs.org/learning/ecsql/) query and defines one table in the output data of a report.

### Group Query

The `query` parameter of a Group supports ECSql and ECClassIds.

If a valid ECSql query is given and the selected class is `bis.Element`, or if it is a descendant of the class `bis.Element`, the only required column is `ECInstanceId`.

- `SELECT * FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT * FROM Building.Beam` is a valid query
- `SELECT ECInstanceId FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECInstanceId FROM Building.Beam` is valid
- `SELECT ECClassId FROM bis.Element` is _not_ a valid query because ECInstanceId column is missing
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECClassId FROM Building.Beam` is _not_ valid because ECInstanceId column is missing
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.ECInstanceId FROM bis.Element E JOIN Building.BeamAspect A ON A.Element.id = E.ECInstanceId` is _not_ valid because the selected `ECInstanceId` is of the aspect, not the element
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id FROM Building.BeamAspect` is _not_ valid because the selected column's name is not `ECInstanceId`
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id ECInstanceId FROM Building.BeamAspect` is valid

In all other cases when providing an ECSql query it is required to select `ECInstanceId`, `ECClassId`, and all other columns that you are planning to use for mapping. If only `ECInstanceId` and `ECClassId` are selected and other columns are used for mapping, those columns will be filled with `null` values. If either `ECInstanceId` or `ECClassId` column is not selected, the query will not produce any output.

If the `query` parameter does not contain a valid ECSql query, then it must be equal to `bis.Element`, `bis.ElementAspect`, or any of their descendants.

The ECClassId format `{schemaName}:{schemaItemName}` where `schemaName` does not contain a 3-part version number is supported.

The ECClassId format `{schemaName}.{schemaItemName}` is supported.

The ECClassId format `{schemaAlias}:{schemaItemName}` where `schemaAlias` is the alias of a `schemaName` is supported.

The ECClassId format `{schemaFullName}:{schemaItemName}` where `schemaFullName` contains a 3-part version number is _not_ supported.

When the given ECClassId is equal to `bis.Element` or is one of its descendants, then all elements with the ECClassId will be selected.

When the given ECClassId is equal to `bis.ElementAspect` or is one of its descendants, then all elements that have such aspect will be selected.

When the given ECClassId is none of the above, the query will not produce any output.

- If a class `Building.Beam` does not have any subclasses and the `query` parameter is set to `Building.Beam`, then all elements with ECClassIds of `Building.Beam` will be selected
- If there is a class `Building.StructuralMember` which has 2 subclasses `Building.Beam` and `Building.Column`, and the `query` parameter is set to `Building.StructuralMember`, then all elements with ECClassIds of `Building.StructuralMember`, `Building.Beam`, and `Building.Column` will be selected
- If a class `Building.BeamAspect` inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.BeamAspect`, then all elements that have a `Building.BeamAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId
- If there is class `Building.StructuralMemberAspect` which has 2 subclasses `Building.BeamAspect` and `Building.ColumnAspect`, the `Building.StructuralMemberAspect` class inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.StructuralMemberAspect`, then all elements that have `Building.StructuralMemberAspect`, `Building.BeamAspect`, or `Building.ColumnAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId

If different queries are needed for a single output table, then create multiple Groups with those different queries but with the same name for each Group. That will cause results of all these queries to be concatenated into a single output table. The output table will have column list equal to a union of all GroupProperties of Groups with the same name.

### Rate limits

All iTwin Platform API operations have a rate limit. For more documentation on that visit [Rate limits and quotas](https://developer.bentley.com/apis/overview/rate-limits/) page.

### Extraction row limiting

Mappings created or modified by using the "Try it out" function can only extract a maximum of 100 rows for each group. Mapping modification is considered any POST/DELETE/PATCH/PUT request to any endpoint with the tag "Mappings" or if the URL contains {mappingId}.

---


create-group

Id of the Mapping for which to create a new Group.

---

Creates a GroupProperty for a Group. Each GroupProperty defines a column of mapped data.

### Mapping ECProperties

GroupProperties define mappings from ECProperties on an iModel to columns. They allow mapping the queried, element, element aspect, or related element properties.

Content of the columns depend on the `ecProperties` field. The `ecProperties` field is a prioritized array which contains `ECProperty` entities. The closer the `ECProperty` is to the array's start, the higher the priority. The priority of `ECProperty` can be changed by reordering the `ecProperties` array. Reading of the `ecProperties` array stops when a valid value is found. For example, if the `ecProperties` array contains two entries and the first entry results in a null or undefined value, it will take the second entry. The value can be undefined if the given ECProperty does not exist. The result column will be filled with a null value if no valid value was found.

Evaluating `ecProperties` is prioritized by:

1. Queried properties
2. Element properties
3. Element aspect properties

Having queried properties as the highest priority allows for constant or complex values to be added to a mapping.

`ECProperty` lookup is defined by three values - `ECSchemaName`, `ECClassName`, and `ECPropertyName`.

`ECSchemaName` and `ECClassName` are used together to create a ECClassId which is the ECClassId of the current row when selecting a property. If the ECClassId of a selected row does not match the `ECSchemaName` and `ECClassName` pair, the value for this `ECProperty` is considered undefined. If the formed ECClassId is of an element aspect, the current selected row is an element and there is only one instance of that element aspect related to the element, the property lookup is done on the element aspect.

`ECSchemaName` and `ECClassName` are case-insensitive.

`ECSchemaName` and `ECClassName` can be set to a wildcard value `*`.

- If the value of `ECSchemaName` is `*` and the value of `ECClassName` is `Beam`, then it will match any `Beam` class from any schema (e.g. `Building.Beam`, `Structural.Beam`, etc.)
- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `*`, then it will match any class from the schema `Building` (e.g. `Building.Beam`, `Building.CurtainWall`, etc.)
- If values of `ECSchemaName` and `ECClassName` are `*`, then it will match any ECClassId (e.g. `Building.Beam`, `Structural.Column`, etc.)
- If either value of `ECSchemaName` or `ECClassName` are `*`, then no element aspect lookup is done

Class inheritance is checked if there is no wildcard value.

- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `StructuralMember`, then it will match any ECClassId which inherits `Building.StructuralMember` (e.g. `Building.Beam` which inherits `Building.StructuralMember`, `Building.Column` which inherits `Building.StructuralMember`, etc)
- If `ECSchemaName` or `ECClassName` is a wildcard, then inheritance will not be checked

Set `ECPropertyName` to a property name that you want to select. The value of `ECPropertyName` can also be a path defining how to find a property. The path segments must be separated by a period (`.`). The path can contain the names of:

- A navigation property
- A struct property
- A string property that happens to contain a string representation of a json object
- A property inside the selected json

Names of properties are not case sensitive. If json object does not have duplicate property names which only differ in letter casing, then those json properties are not case sensitive. We recommend treating json properties as case sensitive.

- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category` or `category`, then the whole value `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` will be selected
- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category.id`, then only the `id` value `0x2000000000b` will be selected
- If `Category` property is a navigation property and it points to a row that has a property `CodeValue` that we want to select, the `ECPropertyName` should be set to `Category.CodeValue`
- If `Model` property is a navigation property and it points to a row that has a property `JsonProperties` with a value `{"formatter":{"mastUnit":{"label":"m"}}}` and we want to select the master unit label, the `ECPropertyName` should be set to `Model.JsonProperties.formatter.mastUnit.label`. The result will be `m`

### Calculation Types

Calculation types that start with `BoundingBox` use element aligned bounding boxes. They can be used for approximations of geometric element dimensions when there are no available properties that would have exact dimensions. Some errors may occur due to bounding boxes not being a perfect fit for the surrounded element.

List of all available calculation types:

- `Length` - calculation of a linear element length or a perimeter of a geometric element that does not have a volume. For elements that have a volume use BoundingBox calculations to approximate the length.
- `Area` - calculation of a geometric element's surface area.
- `Volume` - calculation of a geometric element's volume.
- `BoundingBoxLongestEdgeLength` - calculation that gives the longest edge length of an element aligned bounding box.
- `BoundingBoxIntermediateEdgeLength` - calculation that gives the edge length that is not the longest nor the shortest of an element aligned bounding box.
- `BoundingBoxShortestEdgeLength` - calculation that gives the shortest edge length of an element aligned bounding box.
- `BoundingBoxDiagonalLength` - calculation that gives the distance between 2 opposite corners of the element aligned bounding box.
- `BoundingBoxLongestFaceDiagonalLength` - calculation that gives the longest distance between 2 opposite corners of a face on the element aligned bounding box.
- `BoundingBoxIntermediateFaceDiagonalLength` - calculation that gives the distance between 2 opposite corners of a face on the element aligned bounding box that is not the longest nor the shortest.
- `BoundingBoxShortestFaceDiagonalLength` - calculation that gives the shortest distance between 2 opposite corners of a face on the element aligned bounding box.

Gets a CustomCalculation for a Group.

### CustomCalculations

CustomCalculation is a type of Group property which contains a formula. CustomCalculation defines a column in the output data that gets filled with the formula evaluation result. The formula is evaluated for each row of the Group's query result during each extraction.

The formula supports using other columns (GroupProperty, CalculatedProperty or CustomCalculation entities) as variables. Recursive formulas are not supported, i.e., formula containing a variable `X` is not supported inside a CustomCalculation with a `propertyName` equal to `X`.

Supported data types:

- Number - describes a real number. When converted to a boolean value in logical operators `0` becomes `false` and all other values become `true`
- Boolean - describes a logical value which is either true or false. When converted to a number in certain operators `true` becomes `1` and `false` becomes `0`
- String - describes text. When converted to a boolean value in logical operators an empty string becomes `false` and all other strings become `true`

All of the supported data types can have no value which means that the value is `null`. Some operations support `null` values but those which do not will return `null` as the result.

Supported operators:

| Symbol | Name | Precedence | Associativity | Operand Types | Can receive null | Result |
|--|--|--|--|--|--|--|
| Unary `-` | Unary negation | 9 | Right | Numbers and booleans | No | Number |
| `!` | Logical not | 9 | Right | All data types | No | Boolean |
| `**` | Exponentiation | 8 | Right | Numbers and booleans | No | Number |
| `*` | Multiplication | 7 | Left | Numbers and booleans | No | Number |
| `/` | Division | 7 | Left | Numbers and booleans | No | Number |
| `%` | Remainder | 7 | Left | Numbers and booleans | No | Number |
| `+` | Addition | 6 | Left | All data types | No | Number or string if one of the operands is a string |
| Binary `-` | Subtraction | 6 | Left | Numbers and booleans | No | Number |
| `<` | Less than | 5 | Left | All data types | No | Boolean |
| `<=` | Less than or equal | 5 | Left | All data types | No | Boolean |
| `>` | Greater than | 5 | Left | All data types | No | Boolean |
| `>=` | Greater than or equal | 5 | Left | All data types | No | Boolean |
| `==` | Equality | 4 | Left | All data types | Yes | Boolean |
| `!=` | Inequality | 4 | Left | All data types | Yes | Boolean |
| `&&` | Logical and | 3 | Left | All data types | No | Boolean |
| `\|\|` | Logical or | 2 | Left | All data types | No | Boolean |

Gets all CustomCalculations for a Group.

### CustomCalculations

CustomCalculation is a type of Group property which contains a formula. CustomCalculation defines a column in the output data that gets filled with the formula evaluation result. The formula is evaluated for each row of the Group's query result during each extraction.

The formula supports using other columns (GroupProperty, CalculatedProperty or CustomCalculation entities) as variables. Recursive formulas are not supported, i.e., formula containing a variable `X` is not supported inside a CustomCalculation with a `propertyName` equal to `X`.

Supported data types:

- Number - describes a real number. When converted to a boolean value in logical operators `0` becomes `false` and all other values become `true`
- Boolean - describes a logical value which is either true or false. When converted to a number in certain operators `true` becomes `1` and `false` becomes `0`
- String - describes text. When converted to a boolean value in logical operators an empty string becomes `false` and all other strings become `true`

All of the supported data types can have no value which means that the value is `null`. Some operations support `null` values but those which do not will return `null` as the result.

Supported operators:

| Symbol | Name | Precedence | Associativity | Operand Types | Can receive null | Result |
|--|--|--|--|--|--|--|
| Unary `-` | Unary negation | 9 | Right | Numbers and booleans | No | Number |

Gets a Group for a Mapping.

### Group Query

The `query` parameter of a Group supports ECSql and ECClassIds.

If a valid ECSql query is given and the selected class is `bis.Element`, or if it is a descendant of the class `bis.Element`, the only required column is `ECInstanceId`.

- `SELECT * FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT * FROM Building.Beam` is a valid query
- `SELECT ECInstanceId FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECInstanceId FROM Building.Beam` is valid
- `SELECT ECClassId FROM bis.Element` is _not_ a valid query because ECInstanceId column is missing
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECClassId FROM Building.Beam` is _not_ valid because ECInstanceId column is missing
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.ECInstanceId FROM bis.Element E JOIN Building.BeamAspect A ON A.Element.id = E.ECInstanceId` is _not_ valid because the selected `ECInstanceId` is of the aspect, not the element
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id FROM Building.BeamAspect` is _not_ valid because the selected column's name is not `ECInstanceId`
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id ECInstanceId FROM Building.BeamAspect` is valid

In all other cases when providing an ECSql query it is required to select `ECInstanceId`, `ECClassId`, and all other columns that you are planning to use for mapping. If only `ECInstanceId` and `ECClassId` are selected and other columns are used for mapping, those columns will be filled with `null` values. If either `ECInstanceId` or `ECClassId` column is not selected, the query will not produce any output.

If the `query` parameter does not contain a valid ECSql query, then it must be equal to `bis.Element`, `bis.ElementAspect`, or any of their descendants.

The ECClassId format `{schemaName}:{schemaItemName}` where `schemaName` does not contain a 3-part version number is supported.

The ECClassId format `{schemaName}.{schemaItemName}` is supported.

The ECClassId format `{schemaAlias}:{schemaItemName}` where `schemaAlias` is the alias of a `schemaName` is supported.

The ECClassId format `{schemaFullName}:{schemaItemName}` where `schemaFullName` contains a 3-part version number is _not_ supported.

When the given ECClassId is equal to `bis.Element` or is one of its descendants, then all elements with the ECClassId will be selected.

When the given ECClassId is equal to `bis.ElementAspect` or is one of its descendants, then all elements that have such aspect will be selected.

When the given ECClassId is none of the above, the query will not produce any output.

- If a class `Building.Beam` does not have any subclasses and the `query` parameter is set to `Building.Beam`, then all elements with ECClassIds of `Building.Beam` will be selected
- If there is a class `Building.StructuralMember` which has 2 subclasses `Building.Beam` and `Building.Column`, and the `query` parameter is set to `Building.StructuralMember`, then all elements with ECClassIds of `Building.StructuralMember`, `Building.Beam`, and `Building.Column` will be selected
- If a class `Building.BeamAspect` inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.BeamAspect`, then all elements that have a `Building.BeamAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId
- If there is class `Building.StructuralMemberAspect` which has 2 subclasses `Building.BeamAspect` and `Building.ColumnAspect`, the `Building.StructuralMemberAspect` class inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.StructuralMemberAspect`, then all elements that have `Building.StructuralMemberAspect`, `Building.BeamAspect`, or `Building.ColumnAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId

If different queries are needed for a single output table, then create multiple Groups with those different queries but with the same name for each Group. That will cause results of all these queries to be concatenated into a single output table. The output table will have column list equal to a union of all GroupProperties of Groups with the same name.

### Mapping ECProperties

GroupProperties define mappings from ECProperties on an iModel to columns. They allow mapping the queried, element, element aspect, or related element properties.

Content of the columns depend on the `ecProperties` field. The `ecProperties` field is a prioritized array which contains `ECProperty` entities. The closer the `ECProperty` is to the array's start, the higher the priority. The priority of `ECProperty` can be changed by reordering the `ecProperties` array. Reading of the `ecProperties` array stops when a valid value is found. For example, if the `ecProperties` array contains two entries and the first entry results in a null or undefined value, it will take the second entry. The value can be undefined if the given ECProperty does not exist. The result column will be filled with a null value if no valid value was found.

Evaluating `ecProperties` is prioritized by:

1. Queried properties
2. Element properties
3. Element aspect properties

Having queried properties as the highest priority allows for constant or complex values to be added to a mapping.

`ECProperty` lookup is defined by three values - `ECSchemaName`, `ECClassName`, and `ECPropertyName`.

`ECSchemaName` and `ECClassName` are used together to create a ECClassId which is the ECClassId of the current row when selecting a property. If the ECClassId of a selected row does not match the `ECSchemaName` and `ECClassName` pair, the value for this `ECProperty` is considered undefined. If the formed ECClassId is of an element aspect, the current selected row is an element and there is only one instance of that element aspect related to the element, the property lookup is done on the element aspect.

`ECSchemaName` and `ECClassName` are case-insensitive.

`ECSchemaName` and `ECClassName` can be set to a wildcard value `*`.

- If the value of `ECSchemaName` is `*` and the value of `ECClassName` is `Beam`, then it will match any `Beam` class from any schema (e.g. `Building.Beam`, `Structural.Beam`, etc.)
- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `*`, then it will match any class from the schema `Building` (e.g. `Building.Beam`, `Building.CurtainWall`, etc.)
- If values of `ECSchemaName` and `ECClassName` are `*`, then it will match any ECClassId (e.g. `Building.Beam`, `Structural.Column`, etc.)
- If either value of `ECSchemaName` or `ECClassName` are `*`, then no element aspect lookup is done

Class inheritance is checked if there is no wildcard value.

- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `StructuralMember`, then it will match any ECClassId which inherits `Building.StructuralMember` (e.g. `Building.Beam` which inherits `Building.StructuralMember`, `Building.Column` which inherits `Building.StructuralMember`, etc)
- If `ECSchemaName` or `ECClassName` is a wildcard, then inheritance will not be checked

Set `ECPropertyName` to a property name that you want to select. The value of `ECPropertyName` can also be a path defining how to find a property. The path segments must be separated by a period (`.`). The path can contain the names of:

- A navigation property
- A struct property
- A string property that happens to contain a string representation of a json object
- A property inside the selected json

Names of properties are not case sensitive. If json object does not have duplicate property names which only differ in letter casing, then those json properties are not case sensitive. We recommend treating json properties as case sensitive.

- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category` or `category`, then the whole value `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` will be selected
- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category.id`, then only the `id` value `0x2000000000b` will be selected
- If `Category` property is a navigation property and it points to a row that has a property `CodeValue` that we want to select, the `ECPropertyName` should be set to `Category.CodeValue`
- If `Model` property is a navigation property and it points to a row that has a property `JsonProperties` with a value `{"formatter":{"mastUnit":{"label":"m"}}}` and we want to select the master unit label, the `ECPropertyName` should be set to `Model.JsonProperties.formatter.mastUnit.label`. The result will be `m`

get-groupproperty

---

Gets all Groups for a Mapping.

### Group Query

The `query` parameter of a Group supports ECSql and ECClassIds.

If a valid ECSql query is given and the selected class is `bis.Element`, or if it is a descendant of the class `bis.Element`, the only required column is `ECInstanceId`.

- `SELECT * FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT * FROM Building.Beam` is a valid query
- `SELECT ECInstanceId FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECInstanceId FROM Building.Beam` is valid
- `SELECT ECClassId FROM bis.Element` is _not_ a valid query because ECInstanceId column is missing
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECClassId FROM Building.Beam` is _not_ valid because ECInstanceId column is missing
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.ECInstanceId FROM bis.Element E JOIN Building.BeamAspect A ON A.Element.id = E.ECInstanceId` is _not_ valid because the selected `ECInstanceId` is of the aspect, not the element
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id FROM Building.BeamAspect` is _not_ valid because the selected column's name is not `ECInstanceId`
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id ECInstanceId FROM Building.BeamAspect` is valid

In all other cases when providing an ECSql query it is required to select `ECInstanceId`, `ECClassId`, and all other columns that you are planning to use for mapping. If only `ECInstanceId` and `ECClassId` are selected and other columns are used for mapping, those columns will be filled with `null` values. If either `ECInstanceId` or `ECClassId` column is not selected, the query will not produce any output.

If the `query` parameter does not contain a valid ECSql query, then it must be equal to `bis.Element`, `bis.ElementAspect`, or any of their descendants.

The ECClassId format `{schemaName}:{schemaItemName}` where `schemaName` does not contain a 3-part version number is supported.

The ECClassId format `{schemaName}.{schemaItemName}` is supported.

The ECClassId format `{schemaAlias}:{schemaItemName}` where `schemaAlias` is the alias of a `schemaName` is supported.

The ECClassId format `{schemaFullName}:{schemaItemName}` where `schemaFullName` contains a 3-part version number is _not_ supported.

When the given ECClassId is equal to `bis.Element` or is one of its descendants, then all elements with the ECClassId will be selected.

When the given ECClassId is equal to `bis.ElementAspect` or is one of its descendants, then all elements that have such aspect will be selected.

When the given ECClassId is none of the above, the query will not produce any output.

- If a class `Building.Beam` does not have any subclasses and the `query` parameter is set to `Building.Beam`, then all elements with ECClassIds of `Building.Beam` will be selected
- If there is a class `Building.StructuralMember` which has 2 subclasses `Building.Beam` and `Building.Column`, and the `query` parameter is set to `Building.StructuralMember`, then all elements with ECClassIds of `Building.StructuralMember`, `Building.Beam`, and `Building.Column` will be selected
- If a class `Building.BeamAspect` inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.BeamAspect`, then all elements that have a `Building.BeamAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId
- If there is class `Building.StructuralMemberAspect` which has 2 subclasses `Building.BeamAspect` and `Building.ColumnAspect`, the `Building.StructuralMemberAspect` class inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.StructuralMemberAspect`, then all elements that have `Building.StructuralMemberAspect`, `Building.BeamAspect`, or `Building.ColumnAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId

If different queries are needed for a single output table, then create multiple Groups with those different queries but with the same name for each Group. That will cause results of all these queries to be concatenated into a single output table. The output table will have column list equal to a union of all GroupProperties of Groups with the same name.

Updates a CalculatedProperty for a Group.

### Calculation Types

Calculation types that start with `BoundingBox` use element aligned bounding boxes. They can be used for approximations of geometric element dimensions when there are no available properties that would have exact dimensions. Some errors may occur due to bounding boxes not being a perfect fit for the surrounded element.

List of all available calculation types:

- `Length` - calculation of a linear element length or a perimeter of a geometric element that does not have a volume. For elements that have a volume use BoundingBox calculations to approximate the length.
- `Area` - calculation of a geometric element's surface area.
- `Volume` - calculation of a geometric element's volume.
- `BoundingBoxLongestEdgeLength` - calculation that gives the longest edge length of an element aligned bounding box.
- `BoundingBoxIntermediateEdgeLength` - calculation that gives the edge length that is not the longest nor the shortest of an element aligned bounding box.
- `BoundingBoxShortestEdgeLength` - calculation that gives the shortest edge length of an element aligned bounding box.
- `BoundingBoxDiagonalLength` - calculation that gives the distance between 2 opposite corners of the element aligned bounding box.
- `BoundingBoxLongestFaceDiagonalLength` - calculation that gives the longest distance between 2 opposite corners of a face on the element aligned bounding box.
- `BoundingBoxIntermediateFaceDiagonalLength` - calculation that gives the distance between 2 opposite corners of a face on the element aligned bounding box that is not the longest nor the shortest.
- `BoundingBoxShortestFaceDiagonalLength` - calculation that gives the shortest distance between 2 opposite corners of a face on the element aligned bounding box.

### Extraction row limiting

Mappings created or modified by using the "Try it out" function can only extract a maximum of 100 rows for each group. Mapping modification is considered any POST/DELETE/PATCH/PUT request to any endpoint with the tag "Mappings" or if the URL contains {mappingId}.

update-calculatedproperty

Id of the CalculatedProperty to be updated.

Updated a CalculatedProperty successfully.

---

Updates a CustomCalculation for a Group.

### CustomCalculations

CustomCalculation is a type of Group property which contains a formula. CustomCalculation defines a column in the output data that gets filled with the formula evaluation result. The formula is evaluated for each row of the Group's query result during each extraction.

The formula supports using other columns (GroupProperty, CalculatedProperty or CustomCalculation entities) as variables. Recursive formulas are not supported, i.e., formula containing a variable `X` is not supported inside a CustomCalculation with a `propertyName` equal to `X`.

Supported data types:

- Number - describes a real number. When converted to a boolean value in logical operators `0` becomes `false` and all other values become `true`
- Boolean - describes a logical value which is either true or false. When converted to a number in certain operators `true` becomes `1` and `false` becomes `0`
- String - describes text. When converted to a boolean value in logical operators an empty string becomes `false` and all other strings become `true`

All of the supported data types can have no value which means that the value is `null`. Some operations support `null` values but those which do not will return `null` as the result.

Supported operators:

| Symbol | Name | Precedence | Associativity | Operand Types | Can receive null | Result |
|--|--|--|--|--|--|--|
| Unary `-` | Unary negation | 9 | Right | Numbers and booleans | No | Number |
| `!` | Logical not | 9 | Right | All data types | No | Boolean |
| `**` | Exponentiation | 8 | Right | Numbers and booleans | No | Number |
| `*` | Multiplication | 7 | Left | Numbers and booleans | No | Number |
| `/` | Division | 7 | Left | Numbers and booleans | No | Number |
| `%` | Remainder | 7 | Left | Numbers and booleans | No | Number |
| `+` | Addition | 6 | Left | All data types | No | Number or string if one of the operands is a string |
| Binary `-` | Subtraction | 6 | Left | Numbers and booleans | No | Number |
| `<` | Less than | 5 | Left | All data types | No | Boolean |
| `<=` | Less than or equal | 5 | Left | All data types | No | Boolean |
| `>` | Greater than | 5 | Left | All data types | No | Boolean |
| `>=` | Greater than or equal | 5 | Left | All data types | No | Boolean |
| `==` | Equality | 4 | Left | All data types | Yes | Boolean |
| `!=` | Inequality | 4 | Left | All data types | Yes | Boolean |
| `&&` | Logical and | 3 | Left | All data types | No | Boolean |
| `\|\|` | Logical or | 2 | Left | All data types | No | Boolean |

Parenthesis `(` and `)` can be used to change the precedence of operations. Variables, constants, and functions have a precedence of 1 and left associativity.

Supported constants:

- `E` - Euler's constant and the base of natural logarithms (approx. 2.718)
- `LN2` - natural logarithm of 2 (approx. 0.693)
- `LN10` - natural logarithm of 10 (approx. 2.303)

Examples of supported formulas:

- `min(A * B, B * C, A * C)` - if `A`, `B`, and `C` are 3 different lengths of box edges, then this formula will result in the smallest side surface area of that box
- `min * max` - formula does not have parenthesis after function names, so the `min` and `max` operands are treated as variables (other columns), not as functions. If the Group has columns `min` and `max`, and their values are `2` and `5`, then the result of this formula is `10` for that row
- `2 ** 3` - 2 raised to the power of 3. Result will be 8. This can also be written as `pow(2, 3)`
- `min(cos(X), sin(X))` - function nesting is supported

- `A * B + C` - same as `(A * B) + C`
- `padend(concat(A, '\\', touppercase(substring(B, 4))), C, D)` - the result of `concat`, which concatenates variable `A`, string literal `\` and `uppercase` `substring` of variable `B` from index `4`, is padded in the end with the target length of `C` with a pad string of variable `D`
- `charat(trim(A), B)` - gets the character of a trimmed string variable `A` that is at index `B`
- `if(A > B, A, B)` - if `A` is greater than `B` then the result is `A` else it is `B`
- `ifnullorempty(A, 'B = ') + B` - if variable `A` is null or empty then the result of `ifnullorempty` function is the string literal `B = ` else it is variable `A`. Then the final formula result is the addition of the result of `ifnullorempty` function and variable `B`
- `if(A != null && B != null, A + B, 0)` - if `A` is not null and `B` is not null then the result is the addition of `A` and `B` else it is `0`

### Group Query

The `query` parameter of a Group supports ECSql and ECClassIds.

If a valid ECSql query is given and the selected class is `bis.Element`, or if it is a descendant of the class `bis.Element`, the only required column is `ECInstanceId`.

- `SELECT * FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT * FROM Building.Beam` is a valid query
- `SELECT ECInstanceId FROM bis.Element` is a valid query
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECInstanceId FROM Building.Beam` is valid
- `SELECT ECClassId FROM bis.Element` is _not_ a valid query because ECInstanceId column is missing
- Assuming that class `Building.Beam` is a descendant of the class `bis.Element`, the query `SELECT ECClassId FROM Building.Beam` is _not_ valid because ECInstanceId column is missing
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.ECInstanceId FROM bis.Element E JOIN Building.BeamAspect A ON A.Element.id = E.ECInstanceId` is _not_ valid because the selected `ECInstanceId` is of the aspect, not the element
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id FROM Building.BeamAspect` is _not_ valid because the selected column's name is not `ECInstanceId`
- Assuming that `Building.BeamAspect` is an aspect, the query `SELECT A.Element.id ECInstanceId FROM Building.BeamAspect` is valid

In all other cases when providing an ECSql query it is required to select `ECInstanceId`, `ECClassId`, and all other columns that you are planning to use for mapping. If only `ECInstanceId` and `ECClassId` are selected and other columns are used for mapping, those columns will be filled with `null` values. If either `ECInstanceId` or `ECClassId` column is not selected, the query will not produce any output.

If the `query` parameter does not contain a valid ECSql query, then it must be equal to `bis.Element`, `bis.ElementAspect`, or any of their descendants.

The ECClassId format `{schemaName}:{schemaItemName}` where `schemaName` does not contain a 3-part version number is supported.

The ECClassId format `{schemaName}.{schemaItemName}` is supported.

The ECClassId format `{schemaAlias}:{schemaItemName}` where `schemaAlias` is the alias of a `schemaName` is supported.

The ECClassId format `{schemaFullName}:{schemaItemName}` where `schemaFullName` contains a 3-part version number is _not_ supported.

When the given ECClassId is equal to `bis.Element` or is one of its descendants, then all elements with the ECClassId will be selected.

When the given ECClassId is equal to `bis.ElementAspect` or is one of its descendants, then all elements that have such aspect will be selected.

When the given ECClassId is none of the above, the query will not produce any output.

- If a class `Building.Beam` does not have any subclasses and the `query` parameter is set to `Building.Beam`, then all elements with ECClassIds of `Building.Beam` will be selected
- If there is a class `Building.StructuralMember` which has 2 subclasses `Building.Beam` and `Building.Column`, and the `query` parameter is set to `Building.StructuralMember`, then all elements with ECClassIds of `Building.StructuralMember`, `Building.Beam`, and `Building.Column` will be selected
- If a class `Building.BeamAspect` inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.BeamAspect`, then all elements that have a `Building.BeamAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId
- If there is class `Building.StructuralMemberAspect` which has 2 subclasses `Building.BeamAspect` and `Building.ColumnAspect`, the `Building.StructuralMemberAspect` class inherits from a class `bis.ElementAspect` (is unique or multi aspect) and the `query` parameter is set to `Building.StructuralMemberAspect`, then all elements that have `Building.StructuralMemberAspect`, `Building.BeamAspect`, or `Building.ColumnAspect` attached to them will be selected. This query will _not_ select the aspects themselves, but the elements that they are attached to. The selected elements may have any ECClassId

If different queries are needed for a single output table, then create multiple Groups with those different queries but with the same name for each Group. That will cause results of all these queries to be concatenated into a single output table. The output table will have column list equal to a union of all GroupProperties of Groups with the same name.

Updates a GroupProperty for a Group.

### Mapping ECProperties

GroupProperties define mappings from ECProperties on an iModel to columns. They allow mapping the queried, element, element aspect, or related element properties.

Content of the columns depend on the `ecProperties` field. The `ecProperties` field is a prioritized array which contains `ECProperty` entities. The closer the `ECProperty` is to the array's start, the higher the priority. The priority of `ECProperty` can be changed by reordering the `ecProperties` array. Reading of the `ecProperties` array stops when a valid value is found. For example, if the `ecProperties` array contains two entries and the first entry results in a null or undefined value, it will take the second entry. The value can be undefined if the given ECProperty does not exist. The result column will be filled with a null value if no valid value was found.

Evaluating `ecProperties` is prioritized by:

1. Queried properties
2. Element properties
3. Element aspect properties

Having queried properties as the highest priority allows for constant or complex values to be added to a mapping.

`ECProperty` lookup is defined by three values - `ECSchemaName`, `ECClassName`, and `ECPropertyName`.

`ECSchemaName` and `ECClassName` are used together to create a ECClassId which is the ECClassId of the current row when selecting a property. If the ECClassId of a selected row does not match the `ECSchemaName` and `ECClassName` pair, the value for this `ECProperty` is considered undefined. If the formed ECClassId is of an element aspect, the current selected row is an element and there is only one instance of that element aspect related to the element, the property lookup is done on the element aspect.

`ECSchemaName` and `ECClassName` are case-insensitive.

`ECSchemaName` and `ECClassName` can be set to a wildcard value `*`.

- If the value of `ECSchemaName` is `*` and the value of `ECClassName` is `Beam`, then it will match any `Beam` class from any schema (e.g. `Building.Beam`, `Structural.Beam`, etc.)
- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `*`, then it will match any class from the schema `Building` (e.g. `Building.Beam`, `Building.CurtainWall`, etc.)
- If values of `ECSchemaName` and `ECClassName` are `*`, then it will match any ECClassId (e.g. `Building.Beam`, `Structural.Column`, etc.)
- If either value of `ECSchemaName` or `ECClassName` are `*`, then no element aspect lookup is done

Class inheritance is checked if there is no wildcard value.

- If the value of `ECSchemaName` is `Building` and the value of `ECClassName` is `StructuralMember`, then it will match any ECClassId which inherits `Building.StructuralMember` (e.g. `Building.Beam` which inherits `Building.StructuralMember`, `Building.Column` which inherits `Building.StructuralMember`, etc)
- If `ECSchemaName` or `ECClassName` is a wildcard, then inheritance will not be checked

Set `ECPropertyName` to a property name that you want to select. The value of `ECPropertyName` can also be a path defining how to find a property. The path segments must be separated by a period (`.`). The path can contain the names of:

- A navigation property
- A struct property
- A string property that happens to contain a string representation of a json object
- A property inside the selected json

Names of properties are not case sensitive. If json object does not have duplicate property names which only differ in letter casing, then those json properties are not case sensitive. We recommend treating json properties as case sensitive.

- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category` or `category`, then the whole value `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` will be selected
- If `Category` property is a navigation property with a value of `{"id":"0x2000000000b","relClassName":"BisCore.GeometricElement3dIsInCategory"}` and the `ECPropertyName` is set to `Category.id`, then only the `id` value `0x2000000000b` will be selected
- If `Category` property is a navigation property and it points to a row that has a property `CodeValue` that we want to select, the `ECPropertyName` should be set to `Category.CodeValue`
- If `Model` property is a navigation property and it points to a row that has a property `JsonProperties` with a value `{"formatter":{"mastUnit":{"label":"m"}}}` and we want to select the master unit label, the `ECPropertyName` should be set to `Model.JsonProperties.formatter.mastUnit.label`. The result will be `m`
