This source outlines the seven-step Returnable Transport Packaging (RTP) procurement workflow within an SAP system. The process begins with the creation of master data for both raw materials and containers, followed by the establishment of vendor records and purchasing info records. While initial purchase orders are generated specifically for raw materials, the goods receipt stage accounts for both the primary goods and the returnable packaging. The cycle concludes with invoice verification for the purchased stock and a final transaction to return the empty containers to the supplier. Throughout the guide, specific transaction codes like MM01, MIGO, and MIRO are provided to assist users in navigating each stage of the logistics chain. This structured approach ensures that companies can accurately track reusable assets alongside their standard inventory.
