MDX Topcount with positiveand negative values

Hi everyone,

I've got a problem with the topcount function. Here's an example of what I got:

A query returns 10 values. 5 of them positive, 5 of them negative. Now I want to do a top 8 on this set. I would expect that topcount returns 8 rows. (5 positive ones and 3 negative ones). But actually it returns only 5 - the positive ones! It seems to stop at 0. The documentation states it returns the -highest- values, which also could be negative in my opinion.

Is this by design? Any way to work around?

(A Bottomcount stops at 0 too, only returning the negative ones)

Thank you

Jan F.
