How to do a MDX Except crossjoin dimension query - ssas

Question

Consider the following data. I would like to get the NON{Country:USA & Gender:F} using MDX
- - - - - - - - - - - - - - - - - - - - -
| Country | Gender | Sales |
- - - - - - - - - - - - - - - - - - - - -
USA M 1000
USA F 500
Spain M 200
Spain F 600
What I want to extract would be:
- - - - - - - - - - - - - - - - - - - - -
| Country | Gender | Sales |
- - - - - - - - - - - - - - - - - - - - -
USA M 1000
Spain M 200
Spain F 600
I tried to use crossjoin, union and except to do that, e.g.
WITH SET [Test] AS
[Country].[CountryCode].[USA] * Except ([Gender].members,{[Gender].[GenderCode].[F]}) +
Except([Country].[CountryCode].members, {[Country].[CountryCode].[USA]}) * [Gender].members
SELECT
NON EMPTY [Test] ON ROWS,
{[Measures].[Sales]} ON COLUMNS
FROM [SalesCube]
It works, but may i know if there is any other simpler way to do it ?
Thanks.

If you want to exclude few combinations, you can use Except on the cross join with the excepted combinations as tuples like this:
WITH SET [Test] AS
Except(CrossJoin([Country].[CountryCode].members,
[Gender].members
),
{ ([Country].[CountryCode].[USA], [Gender].[GenderCode].[F]) }
)
...
And syntactically, you an abbreviate CrossJoin as * and Except as -, as well as Union as +, which have the usual rules of precedence (* has higher precendece than - and +):
WITH SET [Test] AS
[Country].[CountryCode].members * [Gender].[GenderCode].members
-
{ ([Country].[CountryCode].[USA], [Gender].[GenderCode].[F]) }
...
