BOXI3.1 - Error during security batch commit

Hi,

Accidentally, I removed some BI roles from CMC -> Authentication, consequently some users were removed from the system. Immediatly, I inserted the BI roles back, but when I tryed to reconfigure "user security" in a existing universe (theirs folders and reports) I received the error message: "An error occurred at the server during security batch commit: Request 0 of type 44 failed with server error : Cannot find the user, group or object 7535".

Did I lost this universe, folders and reports? Is it not possible to recover them?

I appreciate any help.

Best regards,

Cristiane G. Ferreira
