Trying to do day end in Purchase orders and I get an error message stating "An error occurred during day end run: Write ToJCBatchCtrl error: Error occurred while attempting to create the table @J68BCST. Permission denied creating indexfile."

We have just starting using the PO module and have completed several day ends successfully. I've tried twice today and have gotten the same error message. Everyone is out of all of the modules in the office.

Thanks in advance,
Karen
