returns sales order w.r.t billing doc user should not be able to reference
with hope i am putting this requirement so that i can get help from expert like you.
When doing returns sales order w.r.t billing doc, user should not be able to reference the quantity once it is referenced completely.
We sell an Item of Qty 10 pcs, But the customer returns all the Qty-10 pcs. So, the Billing doc is used as reference to create returns sales order.
Billing doc: Qty 10 Pcs
First Return Order is created w.r.t billing doc that has 10 pcs which is fine meaning all the qty -10 pcs sold is return to our warehouse.
But if the User tries to reference again using the same billing doc, Std SAP displays message there are returns item and credit memos but still allows to reference it, which is wrong and user can abuse the system. ( If we sell 10pc , we can take returns for 10pc only and not allow user to cheat and take qty in excess of what is sold )
We don't want the user to reference the same billing doc again and again
