IMsFormulaTransformCoord.TransparentDimensionsCount

Syntax

TransparentDimensionsCount: Integer;

TransparentDimensionsCount: integer;

Description

The TransparentDimensionsCount property returns the number of hidden dimensions in the variable.

Example

Executing the example requires that repository contains time series database with the FC_PARAM identifier. The base contains the COUNTRY attribute referring to the dictionary. The database modeling container contains metamodel with the METAMODEL identifier and model with the MODEL identifier. The parameter referring to the same dictionary as the COUNTRY attribute is set for the metamodel. Add links to the Cubes, Dimensions, Metabase, Ms, Rds system assemblies.

After executing the example parameterized dimension will be set for model variable slice. Information about it is displayed in the console window. If the output variable of the model contains hidden dimensions, the data about it is also displayed in the console.
