Hi Venkat,
there are several notes about this error, so please see the SAP notes writing the error and selecting MS version.
Only one is difficult to find by searching, this because it's related with multiserver, if this is your case you will see that the error appears if you process one or more dimension and after you refresh a report. The error is caused by a desynchronization between application multiserver and DB server and normally this disappear the next day, if you dont want to waite the next day a workaround is to enter in the .dep files on both application server and save these without changes so you will force an alignement, see please 1372498 - Sync the member access security on multi appserver env
Regards
Roberto
