When you create or change a sales order, if you changes fields that are relevant to the profitability segment, the system may not update the corresponding distribution rule of the settlement rule.
If you manually change the requirements type in the sales order, the settlement rule may be completely missing.
To reconcile the data inconsistency for the existing sales orders, use program ZKSAECOR.
If you already settled with the incorrect profitability segment, cancel this settlement first and only then run report ZKSAECOR. Afterwards you can carry out the settlement again.
