Content (required):

Hi all, how to best control applying Payment against a Canceled PO Line. While applying payment against a PO line that was canceled, system provides an Overbill Warning (please see screenshot), which a user can easily ignore and then proceeds to apply payment against the line, after releasing the hold.

Looking for better way(s) to control this than just a Warning or releasing Hold? System must prevent applying payment against the lines that were canceled. This is creating a major audit issue for us. Any help provided in this matter is greatly appreciated.
