which version of OBIEE are you on? looks like BIserver it getting crashed. check the nqserver.log and sawserver.log
I am using OBIEE 126.96.36.199. Yes BI Server is getting crashed and then its getting restarted automatically. I have checked the logs and I found the same error which is displayed while running the report. Nothing extra.
Any Idea what in report could cause the issue. Also the issue is not report specific or column specific. When I add any column to report (or) Also If I rearrange columns in Pivot (or) If I do any simple edit in report, It errors out.
What if if you are not using the column with ISLEAF?
I have few reports with ISLEAF which are working fine as well. However as these reports are erroring out when I edit them, I wasn't able to remove all ISLEAF columns and try.
Actually I am using ISLEAF to hide Account Code and its related rows from all hierarchy levels except for detailed level like shown in below example. Generally If I don't use ISLEAF, The cells(With yellow background) will also contain account codes 123,234,345 repeated for every level.
If this layout can be achieved in any other approach, Please let me know.
How about Account Code is not null filter at report level?
You said that few reports with ISLEAF are working fine, then I would suggest to try do recreate the same report and save it with different name and then try to replicate same error with that new report.
