Undo Posting Utility
Use the Undo Posting utility to reverse ("undo") completed postings.
You cannot unpost a timesheet or labor adjustment run that includes paid hours. If an unposted timesheet includes unit amounts, you must manually delete the unit transaction file.
The Undo Posting utility excludes Accounts Payable Vouchers that are created from purchase orders. This restriction prevents Deltek users from accidentally reversing the posting entries.
If you use multiple companies, the available transaction files are those belonging to the active company.
To undo incomplete postings, use the Incomplete Postings utility.
