Question:
Is there any way to not permit to modify a Stock Transfer PO after the delivery is complete?
When i complete the delivery of the PO i could modify it and add material and change the quantity. I want that when delivery is complete, the PO couldn't be modified.
Thanks.
Answer:
This is the SAP standard. You can always add new items, but you will not be able to change existing items once the history has been updated. Example, you can not set the delivery complete indicator for an item if an addition Delivery has been made out in the Supplying plant's books.
I logged a similar request on the OSS about a week ago, and the above was their reply to me.
