We used profiler to see what the difference was between the Excel Add-in and the cube browser in Analysis Services 2000. We created the same reports in both, and the Excel Add-in did not pass the page filter parameter to the stored procedure that processes the drillthrough request. It works with the Foodmart cube, but the underlying database there is Access, not SQL Server. I have not been able to find this mentioned as a bug in the product, but it seems more major than the known issue of not being able to drillthrough on the non-default partition. Has anybody run into this issue?
