IMsParametrizedDimension.Aggregation

Fore Syntax

Aggregation: IMsParametrizedDimensionAggregation;

Fore.NET Syntax

Aggregation: Prognoz.Platform.Interop.Ms.IMsParametrizedDimensionAggregation;

Description

The Aggregation property returns settings of aggregation for parametrized dimension.

Comments

By default parametrized dimension is not aggregated.

Fore Example

Executing the example requires that the repository contains a modeling container with the MS identifier that contains a metamodel with the METAMODEL_PARAMAGGREGATION identifier. This model must calculate an equation with the MODEL_PARAMAGGREGATION identifier containing one or several factors. The modeling container data source must contain an attribute with the CITY identifier that is a link to a dictionary containing a logical attribute with the ISCAPITAL identifier.

Add links to the Cubes, Dal, Dimensions, Matrix, Metabase, Ms, Rds, Transform system assemblies.

After executing the example a parametrized dimension is set for the first factor, in which aggregation is set up.
