Managing Purchase Order Changes

Sometimes you may need to change a purchase order to respond to production changes. If a purchase order for subcontracting production has been created and a production change requires a change to the purchase order, PeopleSoft Manufacturing sends a purchase order change request to PeopleSoft Purchasing. This request indicates that a purchase order change is required for the subcontracted purchase, and either a purchase order change request is processed or a new purchase order needs to be generated.

You may also need to change the purchase order when any end items have been returned from the supplier as scrap.

If a subcontracted operation has more than one purchase order, the system will not automatically create change requests. You will need to manually create the change requests.

A purchase order change may be necessary when there is a change to:

• The production quantity.

  A quantity change can result from production maintenance as well as from scrapping end items when you're recording completions.

• The actual start date and time or actual due date and time for the production IDs or subcontracted operation.

The purchase order change request is processed by PeopleSoft Purchasing using the Change Load Application Engine process (PO_CHNGLOAD) and the Change Purchase Order Application Engine process (PO_POCHNG).

After you request a purchase order and run the PO Stage load process, the subcontracted operation has an In Process status, after PeopleSoft Purchasing has received and acknowledged the subcontracted operation information.

If you use the background reschedule process to reschedule production with subcontracted operations, and the purchase order date is no longer valid, the system cannot reschedule an In Process purchase order. When running the background reschedule process, you can request that the system check for any production that has an In Process purchase order for subcontracted operations. In this case, the system displays an error message for each instance, unless you decide to skip further in process messages. You can then contact the purchasing department to reschedule the purchase order.

If multiple subcontracted purchase orders exist for the same subcontracted operation, no change order requests will be created from PeopleSoft Manufacturing.
