Returns Line Items
You can process the following business processes involving returns using the xFlow Interface:
Pure returns credit memo
The returns line items are credited (by correcting the balance calculation).
Invoice consisting of delivery and return line items
Delivery line items are billed. Returns line items are credited. The value of the delivery line items is greater than the value of the returns line items.
The line-item data suggestion and calculation of the balance can be performed correctly in the scenarios illustrated above. According to the SAP documentation, the BAPI modules used for parking or posting cannot process invoices that contain returns line items. While processing is generally possible from a technical point of view, the debit/credit flag is set incorrectly (to debit).
Therefore, you must use “Post/Park (SAP)” (MIR7 or MIRO transaction) for parking or posting. If you still want to create the document via BAPI, you will need to correct the debit/credit flag during post-processing. In this case, make the following record type parameter configuration to enable BAPI document creation:
RETURNS_PARK_POST_ACTIVE (value "X" = active)
If you want to park invoices that contain returns line items using the BAPI module and this parameter has not been set, the system will issue a corresponding message and will not generate a document.
