If a hierarchy number is specified, the Dimensions function returns a hierarchy whose zero-based position within the cube is specified hierarchy number.
If a hierarchy name is specified, the Dimensions function returns the specified hierarchy. Typically, you use this string version of the Dimensions function with user-defined functions.
Note
The Measures dimension is always represented by Dimensions(0).
The following examples use the Dimensions function to return the name, count of levels, and count of members of a specified hierarchy, using both a numeric expression and a string expression.
