Duplicate BP Reference Numbers for same document type -need check on orders

Question

Version: (2007A)
Description of requirements:
The user is allowed to create two sales orders for the same customer that have exactly the same BP Reference. When the user invoices one of them and then tries to invoice another, they are  warned that there is already a document of the same type with this reference number. The problem is, they ship the goods out physically before they actually create the invoice document, so that by the time they are entering the invoice in the system, the goods have already been shipped twice, when they should only have been shipped once, If they were warned when they were adding or updating the order, then this could be prevented from happening. Same thing for vendors. Our customers would like to have the check for duplicate BP references on the purchase order as well as on the AP Invoices.
Business needs: Our Clientsu2019 customers are receiving duplicate shipments and this has a negative impact on their business relationship as it creates costly extra work and inconvenience for all.
Examples: Would like the same check that is currently on AR and AP Invoices for the same BP reference number existing already on the same document type implemented on the sales order and purchase order. When the user is adding an invoice for a BP and there is already an invoice for the BP with the same BP reference number, the user is warned and asked if they want to continue.
Current Workaround: None. As our customers often physically ship the goods before creating an invoice from the order, there are duplicate shipments and this is most inconvenient and costly to our customers as well as their customers.
Proposed solution: see above. This is a high priority item for our customers.

hi,
Use SP_TransactionNotification to block sales order & purchase order from adding having duplicate bp reference number.
SAP Note 1258097 - Can the Suppliers Reference number be
made unique? activated approval procedure also for ar invoice.
It may solve problem.
