But while doing so I received a below error while generating the report.
Error Codes: OPR4ONWY:U9IM8TAC:OI2DL65P
The report does not bring back data when run in Answers. It’s an Union Report. All other reports on the same dashboard page (which are no Union Reports) are working as expected. This reports works fine on different Server.
Please let me know what actually is causing this error as there are only few reports left that are not working on upgraded version.
