When a Purchase order is pegged to a production order and has already been confirmed (meaning the vendor has acknowledged and agreed to the terms), rescheduling the related production order—either through job or operation scheduling—unexpectedly changes the PO status from Confirmed back to Approved. This is problematic because it disrupts the procurement process and can cause misalignment with vendors.

Summary:

• The vendor is not notified of the change.
• The purchaser is not automatically informed.
• Action messages (which should prompt the purchaser to review changes) are bypassed.
• The process complicates EDI, version control, and does not align with vendor expectations.

Expected Result

• Confirmed POs should remain confirmed unless the purchaser explicitly decides otherwise.
• Scheduling actions (job or operation) should not alter the status of confirmed POs.
• Purchasers should rely on action messages to decide if vendor communication is needed.
