Transaction Application Reversal (AR80.2)
Use Transaction Application Reversal (AR80.2) to reverse invoices, debit memos, and credit memos after posting. You can reverse posted transactions for open item processing customers only.
Note: If you use the Release form function, AR80.2 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 AR80.2, you will need to run AR180 to process and update the transactions.
