Subcontracting Scenarios

The following scenarios are possible for returns from the subcontractor:

Recursive repair

Samepart with same material number and same serial number

Unit exchange

Differentpart with same material number and different serial number

Modification

Samepart with different material number and same serial number

You cannot change the subcontracting type for a purchase order item from Refurbishment with Unchanged Material Number to Refurbishment with Changed Material Number after you have sent the part to the subcontractor.

This scenario is supported only if the original and modified materials are fully interchangeable (that is they are part of one form-fit-function (FFF) class) or restricted interchangeable. Then you can use the unplanned material exchange (UME) function to carry out the material exchange with the same serial number (the same serial number, but a different material has to be posted back during the goods receipt. This is not typical forUMEfrom a business perspective, but it is technically possible.) For more information aboutUME, see Unplanned Material Exchange .

In exceptional cases where an unplanned modification is required, we recommend you do the following:

Reverse the transfer posting to the vendor using movement type 542 in the Transfer Posting function (transaction code MB1B) or using the Reverse Goods Movement function (transaction code VL09).

Deassign the serial number from the delivery.

Create a new purchase order item with the following details:

Create a new delivery.

Post the transfer posting.

Replacement (unplanned material exchange)

Interchangeablepart with different material number and different serial number

A subcontractor might return a different part as a replacement to the part that you originally sent. This replacement can be fully or restricted interchangeable with the original rotable. In the Subcontracting Monitor , you can create subitems for a subcontract purchase order for fully interchangeable and restricted interchangeable parts.

In a replacement scenario, you can replace only fully and restricted interchangeable parts.

You can carry outUMEonly once for a purchase order item.

You cannot carry outUMEfor a manufacturer part number (MPN) subitem that has been created using the MPN functions. For more information about MPN, see Inventory-Managed Manufacturer Part
