  1. Repetitive Manufacturing SAP Best Practices

  2. Purpose, Benefits, and Key Process Steps • Purpose • Repetitive Manufacturing is commonly used when a production process meets the following criteria: • The same or similar products are produced over a lengthy period of time. • The products produced are not manufactured in individually defined lots. Instead, a total quantity is produced over a certain period at a certain rate per part-period. • The products produced always follow the same sequence through the machines and work centers in production. • Routings tend to be simple and do not vary much. • Benefits • Simplified handling of the production process with full cost control • Key Process Steps • Creating Planned Independent Requirements • Material Requirements Planning at Plant Level • In-House Production • Confirming Assembly Activities

  4. Detailed Process Description • Repetitive Manufacturing • Make to stock production REM • Repetitive Manufacturing is in this case a purely for make-to-stock production based on run schedule headers. This means that production is controlled without a direct reference to the sales order. Run schedule quantities determine the dates and quantities. Requirements are created in Demand Management. • Make to stock production REM-Material requirement Planning • The daily MRP run generates planned orders for the material that is to be produced. The system automatically generates purchase requisitions for purchased parts within the 3-month opening period for the planned order. • Make to stock production REM-Planning table • Within the framework of repetitive manufacturing, planning and control is carried out on the basis of time buckets. Starting from the existing requirements situation. • Make to stock production REM-Backflushing • Production completion confirmations are simplified and are made with reference to the material being produced. The completion confirmation includes the backflushing of components and the posting of production costs • Make to stock production REM-Cost Object Controlling • In repetitive manufacturing, cost will be determined per production version via a product cost collector (product cost per period).
