Change Supplier name on apporoved PO

Dear Support,

We have business request to update the approved PO with other Supplier . PO was matched and Paid. Business void the payment cancel the invoice and return the receiving to supplier.

PO status is only Approved now. business want to change the same supplier from Local to Foreign supplier names.

What will be the impact if we update the supplier name from backend.

Regards,

Nadeem
