 Pull List Locate this document in the navigation structure

Purpose

The pull list controls the internal flow of material to supply production. It is assumed that the components required for production have already been produced in-house or procured externally and now merely need to be moved from their current storage location or bin to the production storage location.

The pull list checks the stock situation at the production storage location and calculates the shortfall quantities for the components. Replenishment elements can be created for these shortfall quantities.

Integration
  • The pull list is an integral part of Repetitive Manufacturing and Shop Floor Control .

  • The pull list is integrated with the application component Warehouse Management (WM).

  • If you activate the business function LOG_PP_EWM_MAN , the pull list is integrated with SAP EWM. For more information on the integration Extended Warehouse Management, follow the menu path   SAP Library   SAP ERP Central Component   Logistics   Logistics Execution (LE)   Integration of Extended Warehouse Management   Integration of Extended Warehouse Management into PP   .

    In the area of repetitive manufacturing you must note the following restriction regarding integration with EWM:

    Caution Caution

    For confirmation purposes, only the finished product can be stored at an EWM-managed storage location. The components can be withdrawn from an EWM-managed source storage location and staged in production. However, the production storage location you have assigned to the production supply area must be MM-IM-managed because the system simultaneously posts the issue of the components at the time of confirmation. This goods issue posting is only possible if the production storage location is MM-IM-managed.

    For this reason, using the pull list in conjunction with an EWM system, you can also only trigger the replenishment of release orders whose source storage location is EWM-managed and whose destination storage location is MM-IM-managed.

    End of the caution.
  • The components can be withdrawn for staging from the following storage locations:

  • You have the following options with regard to the staging of the components:

    • Direct stock transfer or stock transfer reservation in an MM-IM-managed storage location

    • Replenishment by setting a kanban to Empty

    • Replenishment via transfer requirements in Warehouse Management

    • Replenishment via deliveries if you are using an SAP EWM system However, this is only possible for release order parts. In the process, the source storage location must be EWM-managed and the destination location (production storage location) must be MM-IM-managed.

  • The basis for replenishment planning is Material Requirements Planning (MRP) or, in conjunction with SAP EWM , the EWM system from which the requirements for the components result. The system takes requirements from run schedule quantities, production order reservations, and manual reservations into account.

Features

You can invoke the pull list via the material to be produced (that is, via the superordinate assembly), via the components, the production line, or the MRP controller, among other ways.

The pull list calculates which requirements there are up to a certain point in time and which stocks are available at the production storage location or production supply area, or which replenishment quantities have already been triggered via the pull list, and thus calculates the shortfall quantity.

You can also use the pull list to generate replenishment elements to cover the calculated shortfall quantity. The system first creates a replenishment proposal for the shortfall quantity The system can post this proposal as a replenishment element (stock transfer reservation, kanban, or transfer requirement in WM, delivery from EWM) or carry out a direct stock transfer.

Restrictions

It is not the primary task of the pull list to determine where the needed components are located. An exception is in the direct stock transfer procedure, where a replenishment storage location must be entered or a replenishment storage location found via the stock determination facility.

Above all, the pull list is responsible for planning material staging (calculating shortfall quantities and triggering replenishment) by generating a work list in the form of replenishment elements. The actual staging is carried out by a warehouse clerk, for example, and is supported by downstreamtransactions based on the replenishment elements.
