If one of the sets in a crossjoin result to be empty, is
there a way to ignore this set and cross join the others?

For example:

The follow MDX produces results

SELECT {Hierarchize({CROSSJOIN({{[Customers].[All
Customers]}},{{[Product].[All Products].[Drink]}})})} on
0 from [Sales]


when the following MDX is excuted no results are returned
(as expected)

SELECT {Hierarchize({CROSSJOIN({{EXCEPT({{[Customers].
[All Customers]}},{{Descendants([Customers].[All
Customers])}})}},{{[Product].[All Products].
[Drink]}})})} on 0 from [Sales]

No result is returned as expected.

Question:

Is there a way to ignore the "emptyness" of the first
set and still display the results from the second set?

thanks
