I tried re-opening this earlier discussion...
"The report filename was empty" rears its ugly head again
... after this error came back; we moved our data source and I had to switch from using the viewer SDK to the engine SDK. Since I haven't seen any replies, I thought I should try creating a new discussion thread. It seems that my report which has parameters will work with the engine/ReportDocument code, but the one without parameters produces the above error. The sample code is in the other thread so I won't re-copy it here unless advised to do so. I really need to get this resolved so any guidance is greatly appreciated.
