I have seen many, many EDI implementations in this space over the years and have yet to come by a single company that has adopted all of the good features available in SAP to bring real value in to the PTP process. In each part of the process, described below, I will highlight exactly what the purpose is for each EDI message or functionality and highlight the benefits for implementing it in the mentioned fashion.
Below, I list the PTP process for a typical replenishment PO where we procure stock via a Purchase Order (PO) to a supplier who delivers the product to our warehouse using one of our 3rd party carriers. The nuances around freight forwarding, drop ship and make to order scenarios are not covered here but are addressed using 90% of these same techniques as well.
