I'm creating my return order with reference from my billing document. my materials are batch managed and on the invoice we have two line items the main item TAN and the 2nd line item for the Batch item category YB99, for the batch.
Now when i copy my invoice to the Return order it copies both line items. which is what i want, since the 2nd line item has the batch number information, my problem is this the line item YB99 is not relevant for pricing. but when it copies to my return order the item category changes to REN and is giving me a message PR00 is mandatory. How can i fix this?
