MethodFromDataSource: TriState;
The MethodFromDataSource property determines whether the method that is set for data aggregation in the source should be used to calculate totals.
This means aggregation is set directly for a fact of the cube (server aggregation). After this property is set to TriState.OnOption, the totals are calculated using the method that is set in IStandardCubeFactBinding.AggregationType . If the element is not bound to a standard fact or the method is undefined, the totals are calculated based on the method that is set in IPrxDataIslandTotals.MethodValue (default value is sum).
