IMDCalculation.SelectionControl

Syntax

SelectionControl: ICubeSelectionControl;

Description

The SelectionControl property returns parameters of controlling dimensions for parameterization of multidimensional calculation.

Example

Executing the example requires that the repository contains a database with the DB identifier, standard parametric cubes with the CUBE_DEST and CUBE_SOUR identifiers. The CUBE_DEST cube as a fact must use a dictionary with the PARAM_DICT identifier.

After executing the example multidimensional calculation on DB server with the the MDCALC identifier is created in the repository root. The CUBE_SOUR cube serves as a source cube, the CUBE_DEST as a destination cube. In multidimensional calculation the parameter, which influences parameter of destination cube dictionary, is created. A controlling dimension is determined for the source cube.
