This function is like the MDX intersect function; it retrieves the members of an initial list, that are also found in the secondary list.
The intersect function is useful for building sets or lists by finding members common to 2 lists. Used in the proper fashion, it is a robust way to performing conjoined operations on multiple list-based functions in a single step.
It is related to the Except method.
This example retrieves all the members in the first 4 Manufacturers that are ALSO in the bottom 50% of manufacturers based on cost:
Intersect( Head(AllMembers([manufacturers].[manufacturer]),4), BottomPercent(AllMembers([manufacturers].[manufacturer]),50, [Measures].[Cost]) )
Using the grid below, the above method would return Acme, Adihash, and Esics:
