Payment Application Reversal (AR80.1)
Use Payment Application Reversal (AR80.1) to mark applications for reversal after they have been posted to the general ledger. You can reverse posted applications for open item processing customers only.
Note: If you use the Release form function, AR80.1 will update the records
following the same logic as Application Reversal Creation (AR180). So you
do not need to run AR180. However, if you do not use the Release form function
on AR80.1, you will need to run AR180 to process and update the transactions.
