AO workbook is not getting saved in server

Hi All,

We are able to open all the Group Reporting related workbooks with correct selection parameters; but when we are trying to save the workbook in the server, system is throwing an error message:

We are not seeing any details in SU53 T-code, nothing coming in trace log, also no dump got generated in ST22 with our ID. Kindly let us know whether anyone has faced this issue.

Regards,

Ayan
