Self update access for completed PO in the MyOrder

Since P2P portal has been retired, Self-Updates in the completed PO should be performed in the "Update completed PO" tab available in MyOrder.
Kindly access the given link and raise a self-request to get the elevated access for the MyOrder to edit any PO. Please select the required option in attestation whichever applicable and submit the request. https://myorder.microsoft.com/#/change-order/adminAccessRequest.
Notes:

1. Changes in the completed PO can be done by PO owner, PO invoice approver, or PO safe approver, or if a MyOrder created PO – the PO submitter (also called PO requester).
2. PO changes can be made at the PO level – close, reopen or change invoice approver.  At the PO Line level – close, reopen, quantity and price decrease, extend delivery date
3. To re-open the previous year POs requestor needs to reach out via FDA.
