I have a normal Parent dimension, "Customers". I have
created a calculated
dimension called "Top 10 Customers"--Sum(TopCount
([Channel].[Customer
Id].Members, 10, [Measures].[Net Revenue]) )

I can't get it to work in either Excel or OWC:

->Excel 2000: when I add the dimenstion to the top, and
select the "Top 10
Customers" value, it crashes Excel with an application
error ("The
instruction at "0x308d03c8" referenced memory ...")

->OWC: when I add the dimension as a filter and expand it,
I see nothing,
just a blank box where you normally would check a
dimension.

Calcuated measures however seem to work just fine.

Any thoughts...?

Thanks in advance.
