IStandardCubeDimension.AggregatorHierarchies

Syntax

AggregatorHierarchies(FactKey: Variant; Destination: IStandardCubeDestination): IMatrixAggregatorModelHierarchies;

Parameters

FactKey. Key of the fact dimension element, for which aggregation must be set up by levels of alternative hierarchy;

Destination. Cube display version for which aggregation must be set.

Description

The AggregatorHierarchies property determines aggregation settings by levels of alternative hierarchy for the specified dimension of cube facts.

Example

Executing the example requires that the repository contains a standard cube with the CUBE identifier. The dimension with the 1 index uses the dictionary with configured alternative hierarchy.

Add links to the Metabase, Cubes, Dimensions, Matrix system assemblies.

Sub UserProc;
Var
    MB: IMetabase;
    Cub: IStandardCube;
    Hiers: IMatrixAggregatorModelHierarchies;
    AggHier: IBasicMatrixAggregator;
    Dim: IStandardCubeDimension;
    Dest: IStandardCubeDestination;
    HierKey: Integer;
Begin
    MB := MetabaseClass.Active;
    // Get cube for edit
    Cub := MB.ItemById("CUBE").Edit As IStandardCube;
    // Get the first cube dimensions
    Dim := Cub.Dimensions.Item(1);
    // Get parameters of cube display version
    Dest := Cub.Destinations.Item(0);
    // Get the list of alternative hierarchies
    Hiers := Dim.AggregatorHierarchies(1, Dest);
    // Add aggregation settings for alternative hierarchy dictionary
    HierKey := Dim.Dimension.Hierarchies.Item(0).Key;
    AggHier := Hiers.Add(HierKey) As IBasicMatrixAggregator;
    // Change aggregation parameters
    AggHier.UseSelection := True;
    AggHier.DefaultLevelAggregation.Operation := BasicAggregatorOperation.Sum;
    // Save changes to cube
    (Cub As IMetabaseObject).Save;
End Sub UserProc;

After executing the example, aggregation parameters for the first alternative hierarchy of the specified dimension are added in the cube:

Aggregation of selected elements in dimension will be enabled.
Aggregation method will be changed to sum.
