Record Balance for Invoice Reductions
For MM documents with invoice reductions, the balance has not been correctly calculated in the Accounting Block.
To enable correct calculation, two new fields have been added to the Accounting Block:
KZMEK (Keywords: "this is an invoice reduction")
RBWWR ("Invoice amount in document currency of vendor invoice")
If the field KZMEK is populated so that the document is flagged as an invoice reduction, then the field RBWWR becomes a mandatory field.
If the indicator Invoice Reduction is set in the SAP GUI, then the amount in the Vend.inv.amnt FC field is prepopulated with the content of the normal amount field (WRBTR) according to the vendor invoice. Then the user can reduce the amount in the invoice by adjusting the invoice amount. For the calculation of the balance, however, the (reduced) invoice amount will no longer be used, but rather the original amount from the vendor invoice (RBWWR). For technical reasons, it is not possible to transfer the invoice reduction fields to the SAP document: These fields are not in the interface of the BAPI_INCOMINGINVOICE_CHANGE.
