Subcontracting - External Processing from Production E2E Process Flow in SAP MM

Picture Description

Subcontracting and external processing are integral components of the production process within SAP ERP system. This flowchart illustrates the sequence of steps involved in managing and executing subcontracting, where a company outsources part of its production processes to external vendors. The flow from the creation of a production order to the final payment encapsulates a complex interaction between purchase requisitions, goods receipt, invoice verification, and financial accounting.

  • Production Order & Purchase Requisition 📄: The process begins with a production order in SAP, which automatically generates a purchase requisition for external services. This document specifies the requirement for subcontracting work.
  • Purchase Order Creation ✒️: The purchase department then creates a Purchase Order (PO) based on the scheduling lines from the purchase requisition, which is informed by the vendor assigned in the info record.
  • Documentation Printing 🖨️: A purchase order or schedule is printed, detailing the subcontracting arrangement. Additionally, for the excise duty aspect, an excise challan and delivery challan are printed, assuming the scenario where subcontracting occurs without the payment of excise duty.
  • Material Shipment & External Services 🚚: Materials are shipped to the vendor, who performs the required external services on them.
  • Goods Receipt & Confirmation 📦: Once services are performed, the external material is shipped back to the plant. This triggers a completion confirmation of the production order and the subsequent goods receipt for the PO.
  • Invoice Verification & Payment 💸: The accounts payable department manages the incoming vendor invoice, verifying it against the goods receipt and purchase order data in SAP. Once the invoice verification is complete, which includes ensuring the Goods Receipt/Invoice Receipt (GR/IR) and Purchase Price Variance (PPV) are correct, payment is processed in financial accounting.
  • Delivery to Production 🔄: Finally, the externally processed material is delivered back to the shop floor, which completes the subcontracting cycle.

This end-to-end SAP process is essential for tracking, managing costs, and ensuring quality control when outsourcing part of the production process. Understanding each step and the documents involved is crucial for a smooth operation and for capitalizing on the efficiency that subcontracting can provide.
