Reversal of
Settlement Runs 
Use
You can use report "RWMBON15" (transaction "MEB0") to reverse settlement documents for arrangements for a whole settlement run. You have the following options:
- Reversal of a whole settlement run for several arrangements
- Reversal of all settlement runs for one arrangement
- Reversal of one settlement run for one arrangement
If several documents are involved in settlement, these are reversed together in a reversal run. For each reversal run, only one run number is assigned for all documents.
You can only reverse the most recent, non-reversed settlement run for each arrangement. This ensures that inconsistent data does not arise as a result of reversing individual documents and then performing settlement accounting again.
You can only use this report to reverse settlement acounting runs for which a settlement run number was assigned, that is to say, as of Release 4.5. In the case of settlement accounting performed in 4.0 or earlier, you must reverse the settlement documents involved in settlement accounting individually. This same restriction applies for credit memos in Invoice Verification that arose as settlement documents in Subsequent Settlement in Release 4.5 or earlier.
