UseDefaultLevelAggregation: Boolean;
The UseDefaultLevelAggregation property determines whether aggregation settings are used for default level.
If the property is set to True, aggregation parameters set in the LevelAggregation property with the parameter value Null are used, otherwise, it is necessary to determine parameters using corresponding properties. The property is set to True by default.
Executing the example requires that the repository contains a cube with the Cube_1 identifier. The cube includes the calendar dimension CALENDAR that contains several levels.
Sub Main;

MB: IMetabase;
MObj: IMetabaseObject;

//Basic aggregation mechanism
ChronAggr := Man.CreateAggregator("ChronologicalMatrixAggregator") As IChronologicalMatrixAggregator;
//For CALENDAR dimension
Dim := StandCub.Dimensions.FindById("CALENDAR");
Lvls := Dim.Dimension.Levels;
ChronAggr.Dimension := Dim.Dimension;
//For default levels
LevAggr := ChronAggr.LevelAggregation(Null);
LevAggr.Operation := ChronologicalAggregatorOperation.Mean;
//For the level next to last
LevAggr := ChronAggr.LevelAggregation(Lvls.Item(Lvls.Count - 2));
LevAggr.UseDefaultLevelAggregation := False;
LevAggr.Operation := ChronologicalAggregatorOperation.UniformDisaggregation;
LevAggr.SourceLevel := Lvls.Item(Lvls.Count - 1);
//Setup of aggregation by the first element of facts dimension
Dest := StandCub.Destinations.Item(0);
Dim.Aggregator(1, Dest) := ChronAggr;
MObj.Save;
End Sub Main;
After executing the example the aggregation for the CALENDAR dimension is set up in the cube. Chronological aggregation mechanism is used. Aggregation with the use of chronological mean is performed for default levels. Own settings are set for the level next to last. Uniform disaggregation to the last level is performed.
