In an OLAP database I work with there is a ‘Location’ hierarchy consisting of the levels Company -> Region -> Area -> Site -> Room. I am using the following MDX to get all the descendants of a particular member at company level.

DESCENDANTS([Location].[Test Company],[Location].[Site], SELF_AND_BEFORE)

I now have a requirement to exclude a particular Region, named ‘Redundant’, from the report. How can I change the above MDX to exclude this particular Region (and all its descendants)? I know this Region will be called ‘Redundant’ but I do not want to hard-code any of the other Region names, as these may change.

  1. The EXCEPT function will take a set, and remove the members you dont want. In your case you need to say:

    EXCEPT( {DESCENDANTS([Location].[Test Company],[Location].[Site], SELF_AND_BEFORE)}, {DESCENDANTS([Location].[Whatever].[Redundant],[Location].[Site], SELF_AND_BEFORE)} )

    This gives you everything in the first set except what you’ve mentioned in the second. It’s easier to understand like this:

    EXCEPT({the set i want}, {a set of members i dont want})

    You shouldnt need to worry about the third (optional) argument: http://msdn.microsoft.com/en-us/library/ms144900.aspx
