IMsDeterministicTransform.AggregateOperands

Syntax

AggregateOperands: IMsCompositeFormulaTermList;

Description

The AggregateOperands property returns the collection of composite terms that are used to calculate aggregation.

Example

Executing the example requires a time series database with the OBJ_RUBRICATOR identifier. INDICATOR is the custom attribute of database time series that refers to the dictionary. NATIONAL_ACCOUNTS is a group of dictionary elements, to which the INDICATOR attribute refers. The modeling container of this time series database must include the MODEL_DETERM model based on time series and calculated using the method of determinate equation.

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

    DimModel := DimObj.Bind As IDimensionModel;
    AggrOper.AggregationAttrKey := DimModel.Attributes.FindById("KEY").Key;
    MObj.Save;
End Sub UserProc;

After executing the example a new term is added to the collection of composite terms that are used on aggregation composition. The group and the key of aggregation attribute are set to it.
