Aggregate(), Sum() functions using calculated members does not work in Analysis Services 2005 SP2 (9.00.3042.00 version) but works in Analysis Services 2000 SP4

When any aggregate function, viz, Aggregate(), Sum() is used on the set of calculated members in Analysis Services 2005 SP2 (9.00.3042.00 version), they are not computing the value and return nulls instead where as the same functions work correctly in Analysis Services 2000 SP4. This seems to be a bug and hope that soon some hotfix would be released.

The workaround for this is not to use these functions for calculated members and rather calculate the values using the mathematical operator.
