SetValueDimension(Instance: IDimInstance): IMsDimIteratorFilteredDimension;
SetValueDimension(Instance: Prognoz.Platform.Interop.Dimensions.IDimInstance): Prognoz.Platform.Interop.Ms.IMsDimIteratorFilteredDimension;
Instance. Data source dimension of data consumer.
The SetValueDimension method sets data source dimension of the data consumer, for which filtering data source value should be linked.
It is used in calculation algorithms on setting up additional filtering by data of calculation block. For additional filtering of data consumer dimension elements by values of the specified attribute, bind values of filtering data source. When additional filtering is used, data consumer dimension elements selection depends on values of selected dimension elements of the selected data source and is taken into account in algorithm calculation.
For details see the Setting Up Data Filtering section.
To specify data source attribute of data consumer, use the IMsDimIterateByDataStub.ValueDimAttr property.
Executing the example requires that the repository contains a calculation algorithm. The calculation algorithm contains a calculation block, in which data consumer and filtering data source are selected for additional filtering of data consumer dimension elements by values of the specified attribute. Make sure that the data consumer contains an MDM dictionary with the DIMENSION identifier, and the calculation algorithm contains a calculation block metamodel with the 12345 key.
Add links to the Metabase, Dimensions, Ms system assemblies.

After executing the example, the value of the KEY attribute contained in the dimension of the data consumer with the DIMENSION identifier to the filtering data source. The console displays name of the bound data consumer dimension.
