Every individual material flow needs a separate material reservation. Therefore, if there are multiple components for the individual operations, you can manually create several reservations (both issue and receipt), (261 and 262). Both reservations are MRP-relevant.

The refurbishment order is used to generate a subcontracting purchase requisition exactly as in normal PM order scenario.

The number of internal operations at the beginning is irrelevant.

The initial goods movement for the internal operation (261 or 313) must be reversed first so that the delivered quantity and the Final Delivery indicator for the refurbishment order are not set instantly after the internal repair activity.

The user must post the reversal movement (262, 314) manually.

Actual data (time, cost) can be recorded for the internal operation. The rotable condition of the component from inventory level must be unserviceable (reflected in the From location data from the main component). Only after completion of the subcontracting part does the component acquire serviceable condition and end up in the To location.

Reversal movements (262, 314) are planned and documented using a separate reservation, for which a separate component also needs to be created in the refurbishment order. This reservation is visible for MRP and allows goods movements. It uses the From location from the main component (plant, storage location, batch, valuation type) as target inventory data, so that after this movement, the component is back in its original state (unserviceable) from which the subcontracting process can deliver it to the vendor.

The goods receipt process for the final subcontracting operations follows exactly the same logic as described in Normal Repair Process: Complete Subcontracting . Hence, the special stock assignment of the purchase order determines if an automated 101 goods movement to the refurbishment order is triggered by the subcontracting goods receipt or not.

If the first operation has an external control key (for example, PM02) and the Subcontracting indicator is set, the subcontracting process is triggered .

The subcontracting goods receipt puts the part back into the unserviceable location ( From ) for the next step.

The first internal operation (after the subcontracting) finds the component in the unserviceable location and the last internal operation posts the normal goods movements for the refurbishment process, concluding with the goods receipt in IW8W .

Typically there should be only one external operation to represent one subcontracting process by one specific vendor/subcontractor. If there are multiple external operations within one order (no matter if they are in a sequence or interrupted by internal operations) they can be linked to different vendors.

The main component is in the component list and is assigned to the first external operation. That means that this is the reservation of the subcontracting purchase order (movement type 543).

The receipt for the subcontracting operation posts the physical update in the inventory depending on the special stock assignment. Either movement type 101 updates the inventory for the purchase order or movement type 262 is required.

The user must set the value of the material provision indicator (MPI) to Rework Material to Subcontractor (value S) for the main component. The reservation entry of the component then has movement type 543 and a purchase requisition is created depending on the reservation relevance.

The delivered quantity of the refurbishment order does not show the subcontracted quantity, the subcontracting purchase order however is visible in the document flow of the refurbishment order as follow-up document.

The IW8W receipt for the internal operation uses the second component as reference, not the header component.

The operations and components, including the MPIs can be loaded from an existing maintenance task list into the order.

All reservations for each operation are MRP-relevant, all demands and receipts are visible in MRP

For each (chain of) internal operation(s) followed by an external operation, a pair of two reservations are created (movement types 261/313 and 262/314).

For an internal operation that is the last one in the order, the normal refurbishment order rules apply. It finds the component in an unserviceable location and posts the normal goods movements for the refurbishment process, concluding with the receipt in IW8W .

For all external operations, the normal subcontracting component is created with MPI S and movement type 543.

The subcontracting goods receipt puts the part back into the unserviceable location ( From ) for the next step. All external operations followed by an internal operation need the automated 262 posting at the end depending on the special stock assignment to physically update the stock after the subcontracting movement.

Only the last operation of the order is different, this is done either with a standard IW8W if the last operation is internal, or the automated 101posting following the logic of Normal Repair Process: Complete Subcontracting if the subcontracting process comes last.
