I try to cache reports on watawarehoue scenario, reports based on analysis services. I use C# application to render every available report to cache it.

It works when some delivery extension is picked: PDF,CSV,HTML4.0,PDF..., however I'd like to use NULL extension, but with that it raises exception in log file (however it seems that caching itself works and there is a record in ExecutionLog with NULL type).

Just changing from NULL to CSV (or any other) will result in no exception in log file.

Even using RS.EXE utility has same effect.
