Few days back one of my colleague installed SSRS 2008 R2 and uploaded few RDLs. When he rendered one of the report, he was getting an error like
The report execution x67wqt55acfewcugepmvrkn has expired or cannot be found. (rsExecutionNotFound)
The said report worked fine in the BIDS but was failing when rendered from Report Manager. I tried to trace the report execution using SQL Profiler but profiler did not receive any call which indicated that the report failed before making call to SQL SERVER. Even googling did not help me😦
After a while, I enabled the remote error property of SSRS (Using SSMS , log into to Report Services. Right click on the instance and select Property -> Advanced) to true
After setting this property, when we rendered the report from Report Manager, we got a new error message saying that date format is invalid.
By default, whenever an error occur, SSRS provides a generic error message like “An error occurred during client rendering….”. But throwing an error like “execution expired” is misleading and cause lot of confusion.
If you happen to get a similar error, try enabling the remote error property and see what is the exact error. Once you are done with the debugging, reset it to False as displaying technical error message to the end-user does not look good. This is just my opinion.
