This flowchart depicts the process flow of receiving and managing Returnable Transport Packaging (RTP) materials in SAP.
Returnable Transport Packaging (RTP) materials are special types of materials used for transportation and storage that are typically owned by the vendor or supplier but used by the customer for a short period. Once the goods are used up, they are returned to the vendor. This concept is crucial in SAP for managing both the economic and logistical aspects of these specific containers.
The process begins with creating Material Master data for the RTP materials and progresses through receiving the RTP materials with or without Purchase Orders, followed by checking available RTP stock, and finally, processing the invoice and payment to the vendor.

Process Steps shown in the image:

1. Material Master for RTP Materials (MM01): The process begins with creating a Material Master record for the RTP material. In the SAP system, RTP materials are classified with the material type “LEIH,” which clearly identifies them as returnable packaging. This distinguishes them from regular materials purchased for production or consumption.
2. Purchase Order (ME21N): A Purchase Order is created to procure the RTP materials from the vendor. The PO specifies the quantity, material details, and delivery date for the RTP items.
3. Goods Receipt Without Purchase Order(MIGO): The RTP materials are received into the system. The movement type “501 M” is used to indicate the arrival of RTP materials without a Purchase Order.
4. Check Stock for RTP Materials(MMBE): After receiving the materials, the available stock of RTP materials is checked using the transaction MMBE. This helps ensure sufficient RTP materials are on hand to meet demand. RTP materials are typically managed as “special stock” in SAP, which means they’re separate from the regular stock of goods that belong to the company. This special stock tracking allows you to keep track of how many RTP containers are currently in circulation.
5. Invoice Receipt(MIRO): The invoice for the received RTP materials is processed in SAP, using the MIRO transaction for invoice receipt.
6. Invoice Processing and Vendor Payment: The invoice is processed, payments are made to the vendor, and the RTP process is completed.
