The user posts the material exchange in the subcontracting monitor ( ADSUBCON ) that updates the purchase order and then the goods receipt for the new material can be posted (as in the standard process).

The goods receipt process is the same as the standard one without material change, therefore the subcontracting 101 goods receipt needs to be followed by 101 for the refurbishment order, which simulates the IW8W functions (setting order delivery status, delivery indicator), depending on the special stock scenario.

In order to be able to post a goods receipt for the refurbishment order, the AFPO record must be automatically updated with the new material number during the subcontracting goods receipt, similar to the logic with the subcontracting purchase order, before the goods receipt for the refurbishment order can be processed.

The unplanned change only works for the full quantity, not partial quantities/deliveries.

In this variant, the refurbishment order header material must be updated to the new material after the subcontracting operation to reflect the unplanned modification. Only then can a subsequent internal process proceed.

If there are still open reservations for additional operations after the subcontracting purchase order is created, the components and the order header must be updated with the new material number . The refurbishment order process then continues with the standard goods movements for the new material number. In the normal process the user must manually update the reservation for the internal operation to the new material, the system can only update the AFPO record automatically when triggered from the ADSUBCON receipt transaction.

When an unplanned goods receipt is followed by a planned material change, then there must be manual user intervention to adjust the planned material change operations and components.

The system triggers a workflow from the subcontracting goods receipt event when a material number changes to a planner of the refurbishment order, so that he knows that he has to manually look into the order, verify all information and if necessary adjust the operation and component data of the order.

If after an internal change, follow-up documents have been already created (for example, a subcontracting purchase order) for the following external process, the following restrictions apply:

If the purchase order has already been created, you cannot change the material.

The subcontracting purchase requisition is automatically updated with a new material from the refurbishment order if it is changed at component level. If a subcontracting purchase order has already been created, you cannot change the material number of the reservation. The user must first delete the purchase order (after checking with the vendor) - and then delete a new purchase order. The deletion of a purchase order cannot be allowed when follow-up movements already took place.

In case of an internal operation with unplanned modification, it is necessary to manually add a second component with a new material that triggers automatic or manual update of following operation/components.
