Function documentationRepair Decision

 

Distribution requirements planning (DRP) makes a repair decision in the following cases:

  • You are using the repair-or-buy function and DRP decided to repair.

  • You decided that a certain location product can only be repaired and not procured.

After DRP has made a decision to repair a location product, it determines whether you should carry out the repair internally or pass the product on to an external subcontractor for repair. The system calculates delivery lead times for the repaired products on the basis of this decision.

Prerequisites

  • If you want an external subcontractor to repair a location product, you have assigned at least one subcontractor to this location product in the master data for external procurement.

  • If you want to repair a location product internally, you have specified a repair time for internal repair in the Repair Time for Internal Repair field on the SPP DRP tab page.

  • For more information about the prerequisites for the repair-or-buy function, see Repair or Buy.

Features

Internal or External Repair

If you repair a location product internally, DRP generates a planned order for internal repair for the location product. DRP transfers this planned order to SAP ERP. SAP ERP generates a refurbishment order from this planned order and then returns the refurbishment order to DRP.

If you repair a location product externally, DRP generates a subcontracting purchase requisition for this location product. DRP transfers this subcontracting purchase requisition to SAP ERP. SAP ERP generates a subcontract order from this subcontracting purchase requisition and then returns the subcontract order to DRP.

In the Type of Repair field in the location product master data on the SPP DRP tab, you can specify whether you would like to repair products internally or pass them on to external subcontractors for repair. The following options are available:

  • Internal Only

    In this case, DRP only allows a location product to be refurbished internally and only generates planned orders for this location product. On the External Procurement – Delivery Schedule Maintenance screen, you cannot create any subcontracting purchase requisitions for this location product manually.

    You access this screen from the SAP Easy Access menu by choosing Start of the navigation path Advanced Planning and Optimization Next navigation step Service Parts Planning (SPP) Next navigation step Planning Next navigation step Distribution Requirements Planning (DRP) Next navigation step Scheduling Agreement Releases End of the navigation path.

  • Internal Preferred (Both Allowed)

    In this case, the system favors internal refurbishing of the location product but does allow external refurbishing. In other words, DRP generates only planned orders for this location product but you can also create subcontracting purchase requisitions manually for the location product on the External Procurement – Delivery Schedule Maintenance screen.

  • External Preferred (Both Allowed)

    In this case, DRP favors external refurbishing of the location product but does allow internal refurbishing. In other words, DRP generates subcontracting purchase requisitions for this location product if you have assigned one or more subcontractors to it. Otherwise, DRP generates planned orders. On the External Procurement – Delivery Schedule Maintenance screen, you can also create subcontracting purchase requisitions and planned orders for this location product manually.

  • External Only

    In this case, the system only allows external refurbishing of the location product. DRP checks whether the location product has been assigned one or more subcontractors. If subcontractors have been assigned, DRP selects the subcontractor with the highest priority and generates a subcontracting purchase requisition for this subcontractor. If none have been assigned, DRP generates the exception No Source of Supply for External Refurbishment/KtS. On the External Procurement – Delivery Schedule Maintenance screen, you cannot create any planned orders for this location product manually.

Delivery Lead Times for Repaired Products

To calculate the delivery lead time for a repaired product, DRP differentiates between products that you repair internally and those that are repaired by a subcontractor. For more information about how the system calculates the delivery lead times, see Calculation of Lead Times in DRP.

Product Number

A product always has the same product number, regardless of whether it is serviceable. You can use versions and sublocations to differentiate between serviceable and unserviceable products. The Business Add-In (BAdI) BAdI: Define Versions and Sublocations for Repair or Buy (/SAPAPO/ROB_VERSION_STLOC) determines both the source and target versions and the source and target sublocations of planned orders and subcontracting purchase requisitions.

Ratio of Unserviceable and Serviceable Products

If you know that one unserviceable product is usually insufficient to create a serviceable product, you can enter the same product in the (recursive) BOM of the primary product as an input product with a factor greater than one. For example, if you know that you require an average of two unserviceable motors to create one serviceable motor, enter the input product Motor with factor 2 in the BOM for the primary product Motor.

Unfulfilled Demand in the Case of Repair

If you have planned for a location product to be repaired only but you cannot fulfill the demand in time using repaired products, DRP checks whether you can still cover the demand in time using repair or buy. If this is possible, DRP generates a DRP Repair or Buy alert (7890).
