Running CR Server 2013 BO4.1...
I had an occurrence today where a report that has been 'working OK' for weeks that, all of a sudden, a dynamic parameter decided it wanted to access a completely different table (it was a selection for supplier code & started returning scrap analysis codes).
I opened the master copy in Crystal Developer & it seemed fine, re-deployed to the server & it was still broken, Opened the report in Dev. again, ran the 'Verify Database' which told me it needed to update the Supplier table, which broke it in Dev. I started from scratch with the original master copy & now it works again.
Has anyone experienced this & is there a known cause?
