Redwood Purchasing:Unable to add a new line with CPA to a Purchase Order in Redwood

Summary:

We have a non-catalog requisition that was converted into a Purchase Order (PO) without a Contract Purchase Agreement (CPA).

We are attempting to create a change order on the PO to add a new line associated with a Contract Purchase Agreement. However, this action cannot be completed using the Redwood Purchase Orders (New) page, and the system displays the error shown below.

Error Message:

You can only update the SourceAgreementId attribute for incomplete purchase orders withdrawn or rejected during the approval process(PO-2055701)

In contrast, the same change order can be created successfully using the Classic Purchase Orders page without any issues.
