I have built a simple cube (not Virtual) with 2 dimensions and a single
measure.

One of the Dimensions is a time dimension.

I have implemented drillthrough on this cube, and am using Analysis Manager
to view the drillthrough data.

When I execute a drillthrough on a value, and I am filtering by Year,
Quarter, or Period I see the drillthrough data.

However when I start to filter on levels lower than the Period level (i.e.
Week or Day) the drillthrough returns an empty dataset.

Any Ideas?

Thanks in Advance

Tony
