JDE 9.1 - Can you change a vendor on a PO if it has been vouchered and then the voucher voided?

Hi -

A PO was generated via a sales order and the incorrect vendor was used. The PO Receipt was vouchered before the error was caught. We have voided the voucher and reversed the receipt but are receiving an error when we try to change the vendor on the PO we get this error.

Ideally, we don't want to generate a new PO but change the vendor on the existing one so we can get the correct vendor paid.

Thanks,

Amy
