Is having the execution supersession available in SAP (allowing automated supersession within SAP ECC) worth the additional effort in configuring MD and in the continual maintenance of this supersession list in SAP?.In either case, SAP will respect the supersession performed in SAP as it would be inherent in the external planning system. However, inventory planners can still use the external planning system user interface to determine the superseded part and then execute the SAP supersession. Planning supersession can be performed in the external planning system with no sustainment supersession data maintained in SAP ECC.Simultaneously, execution supersession can be performed in SAP ECC (for sustainment, production supersession is a different matter). Planning supersession can be performed in the external planning system.They can be for different purposes, however. That is both in SAP ERP and in an external planning system. Supersession logic can be maintained in both the planning system and the execution system. Sales document types (A&D Contract, Repair Quotation, etc.) can be set for MD.вЂќ.MD happens during the sales order process.вЂњInteresting features of material determination: The SAP definition of Material Determination is: In ECC, product substitution functionality is called Material Determination (MD). However, within SAP APO, SAP states that the rule-based Available to Promise check does provide this functionality. Within SAP ECC, supersession is approximated by the Material Determination functionality. Service Parts Management (within SAP APO).Advanced Planning and Scheduling (in SAP APO).However, the question arises about what SAP ECCвЂ™s capabilities are with supersession.ДЄccording to SAP web sources, supersession resides in: When an external system specializing in service parts planning tells SAP what to do, SAP can execute the external systemвЂ™s recommendations. We will use the description of supersession in the MCA Service Parts Optimizer Glossary of Terms: Supersession in SAP ERP In MCA SPO, this supersession is handled by configuring whether the part is subject to supersession and the type of supersession (One Way or Two Way that applies). The supersession configuration in service parts planning systems allows this to be performed automatically during the planning. Obsolesced parts due to engineering changes driven by PLM (Product Lifecycle Management) that need to be replaced by newer versions.Supersession is one of the most important functions in any service parts planning system. You will learn about supersession as well as where it can be found throughout SAP. Supersession and part substitution is a critical component to supply chain planning that is only increasing due to the constant increase in product turnover and product proliferation. Introduction: Getting the Heart of Supersession Where product interchangeability functionality is set up in SAP APO.There are different types of part supersession.Supersession is how parts are set up as interchangeable or substitutable.Last Updated on Maby Shaun Snapp Executive Summary
