Operation subcontracting with material flow support
Complete the following steps to subcontract one or more operations. Together with the subassemblies, material is sent to the subcontractor. The data setup for subcontracting with material supply is described in Setting up operation subcontracting.
-
Create production order
For an item with one or more subcontracted operations, you need a production order. Create a production order manually in Werkstattfertigung, or create a planned production order in Unternehmensplanung, and transfer it to Werkstattfertigung.
For planned production orders in Unternehmensplanung, you can view the production order operations in the Kapazitätsauslastung nach Auftragsvorschlag (cprrp2100m000) session. If applicable, information about subassemblies is indicated on the operation line.
Use the Prognose für Fremdbearbeitung drucken (cprrp2402m000) session to print a list of all subassemblies that are planned to be received from the subcontractor.
-
Release production order
Release the production order in Werkstattfertigung.
In the Produktionsauftrag (tisfc0101m100) session, on the Vorkalkulierter Materialbedarf (ticst0101m000) tab, click Unterbaugruppe anzeigen to view the subassemblies included in the estimated materials:
- For the subassembly that is sent to the subcontractor, a negative quantity is displayed for the operation that precedes the subcontracting operation. A positive quantity is displayed for the subcontracted operation.
-
For the subassembly that is received back from the subcontractor, a negative quantity is displayed for the subcontracted operation. A positive quantity is displayed for the operation that follows the subcontracted operation.
If the subassembly that is received back from the subcontractor is the end item, it will be received in a warehouse specified on the purchase order for this item. Material lines without warehouse orders are generated for the warehouse to denote the subassembly was physically received while administratively the end item is registered on the purchase order.
If the subassembly received from a subcontractor is the end item, proceed to step 9.
-
Generate subcontracting purchase order
A subcontracting purchase order is required to administrate the subcontracting process.
From the Produktionsaufträge (tisfc0501m000) session, start the Einkaufsdokumente für Fremdbearbeitung generieren (tisfc2250m000) session to generate a purchase order. If the Vorige AGs müssen fertiggemeldet sein check box in this session is selected, you must first complete the operations that precede the subcontracted operation before you can generate a purchase order.
In the Einkaufsdokumente für Fremdbearbeitung generieren (tisfc2250m000) session, enter a purchase order type. The activities linked to the purchase order type determine the handling of the subcontracting purchase order. For example, you can choose to insert the Lieferungsaufträge für Fremdleistungen generieren (tdpur4216m000) session, and select the Automatisch check box, so that supply orders are automatically generated.
View the generated purchase order in the Bestellung (tdpur4100m900) session. The order line displays the subassembly that you will receive from the subcontractor after subcontracting.
-
Supply lines and supply orders
After a subcontracting purchase order is generated, you can view the supply lines, in the Bestellung (tdpur4100m900) session or the Bestellung - Materiallieferpositionen (tdpur4116m000) session. Supply lines represent the materials and subassembly that must be shipped to the subcontractor
Supply orders are used to ship the subassembly and material from their warehouses at the manufacturer's location to the administrative warehouse. If supply orders are not created automatically (refer to step 3), run the Lieferungsaufträge für Fremdleistungen generieren (tdpur4216m000) session. Note that the subassembly's supply system, defined in the Artikeldaten nach Lager (whwmd2510m000) session, must be Holprinzip (einzeln).
-
Approve subcontracting purchase order
In the Bestellung (tdpur4100m900) session, click Genehmigen to approve the subcontracting purchase order. For more information, refer to Purchase order approval.
-
Report preceding operations completed
In the Arbeitsgänge fertigmelden (tisfc0130m000) session, complete the operations preceding the subcontracted operations. If you defined a shop floor warehouse, the subassembly is automatically received in the shop floor warehouse. Without shop floor warehouse, the subassembly is received in the warehouse defined in the Artikel - Bestelldaten (tcibd2100m000) session.
In the Für Produktionsauftrag zu entnehmendes Material (ticst0101m100) session, you can check whether the subassembly is issued. In the Bestand nach Spezifikation (whwmd2519m000) session, you can check in which warehouse the subassembly is received.
-
Transfer subassemblies
To ship the subassembly from the job shop or the shop floor warehouse to the subassembly warehouse, carry out the transfer order.
- In the Für Produktionsauftrag zu entnehmendes Material (ticst0101m100) session, select the subassembly that must be sent to the subassembly warehouse. This material line has a negative quantity. In the appropriate menu, click Lageraufträge für Produktion to start the Lageraufträge für Produktion (timfc0101m000) session.
- Select the transfer order with transaction type Entnahme, and click Lagerauftrag - Statusübersicht.
- In the Status Auslagerungspositionen - Übersicht (whinh2129m000) session, carry out the defined activities for the outbound-order line.
-
Send subassemblies and material to subcontractor
The manufacturer must send subassemblies and material to the subcontractor. In LN, the subassemblies and material are sent to the administrative warehouse using an outbound procedure. To do so, you must handle the subassembly's and material's supply orders.
- In the Bestellung (tdpur4100m900) session or the Bestellung - Materiallieferpositionen (tdpur4116m000) session, select the subassembly and material and click Lieferauftrag.
- In the Lagerauftrag (whinh2100m100) session, generate an advice.
- If the orders were not already handled automatically, in the Lagerauftrag (whinh2100m100) session, select the outbound line and click Statusübersicht.
- In the Status Auslagerungspositionen - Übersicht (whinh2129m000) session, carry out the defined activities such as generating and releasing the outbound advice and confirming the shipment.
In some cases, material for subcontracting activities is directly sent by the supplier to the subcontractor. In that case, complete the following steps:
- In the Bestellung (tdpur4100m900) session or the Bestellung - Materiallieferpositionen (tdpur4116m000) session, select the subassembly and material and click Lieferauftrag. A new supply order is generated.
- Select the newly generate order line, and click Genehmigen.
-
Receive purchase order in subassembly warehouse
After subcontracting, the subcontractor sends back the subassemblies. To receive the subassemblies into the subassembly warehouse, you must handle the purchase order. Note that the name of the subassembly sent back by the subcontractor differs from the name of the subassembly you sent to the subcontractor.
Complete the following steps:
- In the Bestellung (tdpur4100m900) session, select the purchase order line of the subassembly sent back by the subcontractor, and on the appropriate menu, click Status Bestellpositionen.
- From the Status Bestellpositionen (tdpur4534m000) session, handle the purchase order according to the defined purchase order procedure. For more information about purchase order handling, refer to Flexible purchase order processing and Overview of purchase order handling.
Note: that when the purchase order is received, LN automatically reports the subcontracted operations as completed. If applicable, the subassembly and the material that you sent with the subassembly are backflushed.
-
Transfer from subassembly warehouse to shop floor warehouse
or the job shop
You may work further on the subassemblies that you received from the subcontractor. Therefore, you must issue the subassemblies to the job shop. In the Für Produktionsauftrag zu entnehmendes Material (ticst0101m100) session, select the subassembly that was sent to you by the subcontractor, which is the subassembly that has a positive quantity. Issue the subassembly to the job shop.
If you use a shop floor warehouse, you must complete a transfer order to ship the subassemblies from the subassembly warehouse to the shop floor warehouse.
- In the Für Produktionsauftrag zu entnehmendes Material (ticst0101m100) session, select the subassembly that was sent to you by the subcontractor, which is the subassembly that has a positive quantity in the Zu entnehmen field.
