IMetaAttributeHierarchySetup.Dimension

Syntax

Description

The Dimension property determines an attribute dimension.

Example

Executing the example requires that the repository contains a time series database with the OBJ_FC identifier.

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

After executing the example names of root elements of attributes hierarchy are displayed in the console window before and after selection is changed.
