Managing Data Mapping
The services for mapping management are available in the TW.AnalysisServices.EventManagementServicesAPI resource.
The following table provides information about the purpose, input parameters, and the result of each service:
Service Name and Purpose
Input Parameters
Result
Parameter Name
Base Type
Description
CreateAutoMappingFromEntity — Maps all the attributes that have matching case-sensitive names with the entity as source, between the model parameters and entity parameters.
sourceEntityName
String
Specifies the name of the source entity on which you want to define mapping.
Returns the fields that were not auto-mapped as a list in the form of an infotable that has the TW.AnalysisServices.ListDataShape data shape.
analysisEventId
String
Specifies the ID of the analysis event for which mapping is to be defined.
mappingType
String
Specifies the type of mapping as one of the following:
inputs
results
prefixAttribute
String
If the property names in the source entity are the same as the field names of the input or result data shapes with a prefix, specify the prefix as the value of this parameter.
forceUpdate
Boolean
Set to true to remove existing mappings and create new mappings.
entityType
String
Specifies the type of entity that the event is to be created on as one of the following:
Thing
Thing template
Thing shape
This parameter is optional.
sourcePath
String
* 
Specify this parameter only if you want to auto-map infotables.
Specifies the path to the selected source infotable from the root of the data shape. If the infotable is a part of nested infotables, the path should be separated by a ‘.’ (dot).
For example: If infotable p to be mapped is a part of nested infotables, Infotable1->Infotable2->p, then sourcePropertyPath is specified as Infotable1.Infotable2.p.
If p is not an infotable, then all fields that fulfil the auto-mapping criteria are mapped.
targetPath
String
* 
Specify this parameter only if you want to auto-map infotables.
Specifies the path to the selected target infotable from the root of the data shape. If the infotable is a part of nested infotables, the path should be separated by a ‘.’ (dot).
For example: If infotable p to be mapped is a part of nested infotables, Infotable1->Infotable2->p, then sourcePropertyPath is specified as Infotable1.Infotable2.p.
If p is not an infotable, then all fields that fulfil the auto-mapping criteria are mapped.
CreateAutoMappingFromEvent — Maps all attributes that have matching case-sensitive names with the event as source, between the model parameters and event parameters.
analysisEventId
String
Specifies the ID of the analysis event for which mapping is to be defined.
Returns the fields that were not auto-mapped as a list in the form of an infotable that has the TW.AnalysisServices.ListDataShape data shape.
prefixAttribute
String
If the property names in the source entity are the same as the field names of the input or result data shapes with a prefix, specify the prefix as the value of this parameter.
forceUpdate
Boolean
Set to true to remove existing mappings and create new mappings.
sourcePath
String
* 
Specify this parameter only if you want to auto-map infotables.
Specifies the path to the selected source infotable from the root of the data shape. If the infotable is a part of nested infotables, the path should be separated by a ‘.’ (dot).
For example: If infotable p to be mapped is a part of nested infotables, Infotable1->Infotable2->p, then sourcePropertyPath is specified as Infotable1.Infotable2.p.
If p is not an infotable, then all fields that fulfil the auto-mapping criteria are mapped.
targetPath
String
* 
Specify this parameter only if you want to auto-map infotables.
Specifies the path to the selected target infotable from the root of the data shape. If the infotable is a part of nested infotables, the path should be separated by a ‘.’ (dot).
For example: If infotable p to be mapped is a part of nested infotables, Infotable1->Infotable2->p, then sourcePropertyPath is specified as Infotable1.Infotable2.p.
If p is not an infotable, then all fields that fulfil the auto-mapping criteria are mapped.

sourcePropertyPath
String
Specifies the path to the sourceProperty from the root of the data shape. This parameter is optional. The value can be an empty string or null if the field is not within an infotable. If the property is a part of nested infotables, the path should be separated by a ‘.’ (dot).
For example: If property p to be mapped is a part of nested infotables, Infotable1->Infotable2->p, then sourcePropertyPath is specified as Infotable1.Infotable2.
sourcePropertyBaseType
Basetypename
Specifies the base type of the source property.
sourcePropertyDS

Specifies the data shape if the sourcePropertyBaseType is an infotable.
targetAnalysisInputDatashapeField
String
Specifies the name of the field from the analysis input data shape to be the target of mapping.
targetAnalysisInputDatashapeFieldPath
String
Specifies the path to the target field from the top-level infotable. The value can be an empty string or null if the field is not within an infotable. If the field is nested within infotables, the path must be separated by a ‘.’ (dot).
For example: If field a to be used in mapping is nested within infotables, [provider].[model].InputParamsDatashape->Level1InfoTable->Level2Info->a, then the path should be Level1InfoTable.Level2Info. Here, you can skip the InputParamsDatshape since it is the default root associated with the inputDatashape of the model.
