SAP MRP: Introduction to "Phantom Assembly"
Download as PPTX, PDF2 likes3,663 views
This document discusses procurement types in SAP MRP, specifically standard procurement vs phantom assemblies. It provides examples of bills of material and procurement types, showing how requirements are generated differently for standard vs phantom materials. For phantom assemblies with procurement type 50, the normal steps of purchasing and charging materials are "superseded", and instead the top-level material is charged directly on the production order without generating requirements for phantom materials.
