The supplier order number must be unique for this sold-to legal entity, supplier, and supplier site.

Summary:

Buyer is seeing following error when trying to do a change order on a PO. The error say, "The supplier order number must be unique for this sold-to legal entity, supplier, and supplier site." This error has also happened when he was trying to acknowledge another PO. This is really strange as he was able to do change orders and acknowledgements on other PO's. Has anyone came across this issue or have any insights to share?

Thanks,

Rohit
