Demand pegged supply orders

If insufficient inventory is available, supply orders can be generated and demand pegged to the demand order requesting allocated inventory. This means the supply order receives the same specification as the demand order. Allocated planned inventory transactions, containing the specifications, are created for the supply orders.

Supply orders for demand orders are generated or manually created from these origins:

  • Order planning runs in Unternehmensplanung. For more information, refer to Order planning, an overview.
  • Sales (demand) orders or schedules in Verkauf.

Demand peg supply orders in Einkauf and Verkauf

The following supply orders can be generated:

  • Purchase orders in the Bestellungen generieren (tdsls4241m000) session.
  • Production orders in the Produktionsaufträge generieren (tdsls4243m000) session.
  • Transfer orders in the Umlagerungsauftrag für VK-Auftrag (tdsls4242s000) session.

Supply orders can be created as follows from the VK-Auftragspositionen (tdsls4101m000) session, or the Geplante Lieferpositionen VK-Auftrag (tdsls4101m100) session:

  • Manually from the stock shortage menu

    When an inventory shortage occurs on the order line, the Bestandsunterdeckung - Menü (tdsls4830s000) session starts. Select Bestellung generieren, Produktionsauftrag generieren, or Umlagerungsauftrag generieren to create a supply order in the relevant session.
  • Manually from the appropriate menu

    When an inventory shortage occurs on the order line, you can click Bestellung generieren, Produktionsauftrag generieren, or Umlagerungsauftrag generieren from the appropriate menu to create a supply order in the relevant session.
  • Automatically at sales order line entry

    When an inventory shortage occurs, a supply order is automatically generated if the relevant session is linked as an automatic activity to the order type in the VK-Auftragsart (tdsls0694m000) session.
Note: 
  • The Bestandsunterdeckung - Menü (tdsls4830s000) session, which can appear for a manually entered sales order, is started only if the total quantity of the allocated inventory and/or demand pegged supply orders is less than the sales order line's ordered quantity.
  • During BOM explosion of the production order, LN can propagate the demand peg to orders for components depending on the Bedarfszuordnung übernehmen field in the Stückliste (tibom1110m000) session.

Demand peg supply orders in Lagerwirtschaft

Supply orders are generated or manually created if insufficient allocated or unallocated inventory is present to fulfil the demand order. If a supply order is generated for the demand order, a specification is also generated for the supply order. This specification has the same characteristics as the specification of the demand order.

When outbound order lines, outbound advice lines, shipment lines, and so on, are created for the demand order during warehouse processing, specifications are generated for these lines. These specifications obtain the specification characteristics of the demand order.

Likewise, the specification characteristics of the supply order are passed on to the specifications generated for the inbound order lines, receipt lines, inspection lines, or handling units.

Lagerwirtschaft parameter settings determine whether:

  • Items received by supply orders become identifiable in inventory through handling units generated for the receipt line of the supply order when the receipt is confirmed. These handling units obtain specifications with characteristics identical to those of the supply order.
  • Specific handling units or anonymous allocated inventory is issued when generating an outbound advice for the demand order. See Inventory allocation levels. LN issues inventory for which the specification characteristics match those of the outbound order lines of the demand order.
  • You can advise unallocated inventory or inventory from a different specification to make up for the missing quantity if insufficient inventory for a particular specification is available to be issued from the warehouse. Whether this is allowed is determined by the Nicht reservierten Bestand vorschlagen and the Bedarfszuordnung der Auslagerungsposition ist verbindlich check box in the Einstellungen für Lagerwirtschaft nach Standort (whwmd2101m000) session. See Allocated or unallocated inventory in the outbound process.

Demand peg supply purchase orders and schedules

A purchase order/schedule is a source of supply for items. Purchased items can be demand pegged to an allocated demand by a specification. During receipt of the item, the characteristics of the specification are copied to the inventory record, which allocates this inventory to the specific demand.

Purchase ordersA purchase order line can be demand pegged if it is generated from the following origins:

  • Electronic Data Interchange (EDI)

    The purchase order line and related specification information is communicated through electronic data interchange (EDI) if the Lieferplanung durch Lieferanten check box is selected in the Planungsbedingungen (tctrm1135m000) session. As a result, the Bedarfszuordnungsart in the Bedingungen für Bedarfszuordnung (tctrm1165m000) session determines the specification's appearance on the purchase order line.
  • Verkauf

    The purchase order is generated in the Bestellungen generieren (tdsls4241m000) session. If a specification is linked to the sales order and the Lieferplanung durch Lieferanten check box is cleared in the Planungsbedingungen (tctrm1135m000) session, the specification of the sales order is copied to the purchase order line.
  • Unternehmensplanung (EP)

    The purchase order is generated from the Auftragsplanung übertragen (cppat1210m000) session. If a specification is linked to the planned order and the Lieferplanung durch Lieferanten check box is cleared in the Planungsbedingungen (tctrm1135m000) session, the specification of the planned order is copied to the purchase order line.
  • Lageraktivitäten (INH)

    The purchase order is generated from the Aufträge generieren (Zeitabhängiger Meldebestand) (whinh2201m000) session. If a specification is linked to the planned inventory transaction and the Lieferplanung durch Lieferanten check box is cleared in the Planungsbedingungen (tctrm1135m000) session, the specification of the planned inventory transaction is copied to the purchase order line.
  • Lagereingang

    The purchase order line is generated automatically for an unexpected warehouse receipt. The specification is copied from the receipt in Lagerwirtschaft.
  • Werkstatt

    The (subcontracting) purchase order line is created from the Einkaufsdokumente für Fremdbearbeitung generieren (tisfc2250m000) session for a subcontracted operation on a production order. The specification is copied from the Vorkalkulierter Materialbedarf (ticst0101m000) session in Fertigung to the Bestellung - Materiallieferpositionen (tdpur4116m000) session in Einkauf.
  • Fremdleistungen - Bestellung

    The (subcontracting) purchase order line is created from the Lieferungsaufträge für Fremdleistungen generieren (tdpur4216m000) session for an order controlled/single system. The specification from the Bestellung - Materiallieferpositionen (tdpur4116m000) session is copied to the purchase order line.
  • Manuell

    For manually entered purchase orders, you can only create a specification in a specific vendor managed inventory (VMI) scenario and a specific subcontracting scenario.

    Before you can manually enter a purchase order for these scenarios, the following check boxes must be selected:

    • Lieferplanung durch Lieferanten in the Planungsbedingungen (tctrm1135m000) session.
    • Bedarfszuordnung erforderlich in the Bedingungen für Bedarfszuordnung (tctrm1165m000) session.

    Both scenarios also require specific settings before you can manually enter purchase orders:

    • VMI scenario

      On the purchase order line, the Zahlung field must be Bezahlung bei Erhalt or Bezahlung bei Verwendung.
    • In the Planungsbedingungen (tctrm1135m000) session, the Referenz an Lieferanten senden check box must be selected.
    • In the Bedingungen für Bedarfszuordnung (tctrm1165m000) session, the Bedarfszuordnungsart must be Auf Basis der internen Referenz.
    • Subcontracting scenario

      On the purchase order line, the Zahlung field must be Keine Zahlung.
    • In the Bedingungen für Bedarfszuordnung (tctrm1165m000) session, the Bedarfszuordnungsart must be Kundenbasiert or Auf Basis der Kundenreferenz.
Note: 

If the purchase order line is a return order line, the specification of the original purchase order line is copied to the return order line.

Purchase schedulesA purchase schedule line can be demand pegged if it is generated from:

  • Lageraktivitäten (INH)

    The purchase schedule is generated from the Aufträge generieren (Zeitabhängiger Meldebestand) (whinh2201m000) session. If a specification is linked to the planned inventory transaction and the Lieferplanung durch Lieferanten check box is cleared in the Planungsbedingungen (tctrm1135m000) session, the specification of the planned inventory transaction is copied to the purchase schedule line.
  • Fremdleistungen - Bestellung

    The (subcontracting) purchase schedule line is created from the Lieferungsaufträge für Fremdleistungen generieren (tdpur4216m000) session for an order controlled/single system. The specification from the Bestellung - Materiallieferpositionen (tdpur4116m000) session is copied to the purchase schedule line.
Note: 

For push schedules, specifications are not used.
