I am using SSRS 2012, querying a 2012 SSAS cube. I have 3 sub-reports that are almost identical, except that they filter for a different Business Unit, and display a different hierarchy.
On sub report renders within seconds when run from Report Server. The other two take a minute or more. But the MDX queries for each, when run in SSMS with appropriate parameters, return data within seconds. When rendering the reports in BIDS (VS 2008), all three get rendered quickly, but that is from cached data in the rdl.data file.
It seems to be the Report Server that is having trouble rendering two of the reports. Is there any way to (easily) differentiate query time vs rendering time for the report server.
One theory is that if the MDX query yields NULL for all the Measure Cells in the result set, then that column is not returned in the result set, which in turn throws errors in the Report Server Log. Could this be the cause of the long processing times?
