Amending Purchase Orders with PSL+

Purchase Orders created in DPO can be amended when changes are required. An amendment creates a new revision while keeping the original P.O. ID.

How to Amend a P.O.

1. Open the P.O. you want to amend.
2. Click the pencil icon.
3. Confirm the amendment process.
4. Update the required information.
5. Click “Amend P.O.”

P.O. Still Awaiting Approval

If the P.O. has not yet reached final approval, the changes synchronize to PSL+ while the P.O. remains:
W – Awaiting Approval

Previously Approved P.O.

If an approved O – Open P.O. is amended, PSL+ changes the status to:
N – Needs Reapproval

After final approval, the P.O. returns to O – Open.

Which Lines Can Be Amended?

DPO only allows amendments to detail lines that are still open in PSL+.
Closed, transferred, or relieved lines cannot be amended.

Important Fields

Changes to important P.O. information, such as the vendor, amount, P.O. number prefix, or currency, require the P.O. to be amended in DPO.

Using the amendment process ensures that:

• The change is properly recorded in the DPO audit trail.
• The existing P.O. and its history are preserved.
• Existing links and synchronization between DPO and PSL+ remain consistent.
• The updated P.O. follows the required approval process before the changes are synchronized to PSL+.
