topcount and filter

Hi All,

we have here a cube, with around 150 GB data.

And a strange query/phenomena.

If I use a topcount function within a session generated set and a time dimension filter under the where condition I am getting something very strange.

The doesnt matter how high the topcount should be it is always less than thet. i.e. if I add topcount(10) it gives back only 4 results.

Removing the time filter fixes this problem. Do you know what it might be?

Thanks a lot!
