Busn. vol. update for reb. arrang. &1 not possible (final sett. effected)

What causes this issue?

Translation: in part identical to NAA040/NAA401
Settlement accounting has already been effected for rebate arrangement
&V1& (arrangement not to be settled periodically).

System Response

Since there is no provision for further settlement accounting with
regard to this arrangement, no business volume data can be updated.

How to fix this error?

Check whether the business volume data is to be taken into account.
If the data should be taken into account, cancel the settlement
document(s). This will cause the status of the arrangement to be reset.
Update the business volumes using the function provided for the purpose
("subsequent business volume update"). You can take account of missing
data as part of a business volume comparison and agreement.
Using the relevant functions/reports, check whether there are any
further open transactions/events (purchase orders/goods receipts/
invoice receipts).
Carry out settlement accounting for the arrangement again.
The condition record has (internal) number &V2&.
