IStandardCubeServerAggregationDimensions.CalcTotal

Syntax

CalcTotal(Index: Integer): Boolean;

Parameters

Index - dimension index.

Description

The CalcTotal property determines whether totals are calculated for the dimension, which index is passed by the Index parameter.

Comments

Available values:

True. Default value. Calculate totals.
False. Do not calculate totals.

Example

Executing the example requires that the repository contains a standard cube with the OBJ_CUBE identifier. This cube must contain two dimensions.

End For;

Debug.WriteLine(s);

End While;

Else

Debug.WriteLine("No data");

End If;

End Sub Main;

After executing the example sum by dimensions is calculated for the cube facts. The calculation matrix is displayed in the console window.
