Phase 05: Jargon Busting

This page explains key jargon from Phase 05 for consultants, analysts, and beginners exploring plant, stock, and MRP configuration in S/4HANA. In short, these terms describe the building blocks SAP uses to plan materials, value stock, and keep warehouses running without guesswork. It matters because clear definitions help prevent confusion when learning configuration concepts, especially when terms sound technical but represent simple ideas. Use it when you need plain-English explanations, and avoid it when you already know the terminology and need deeper technical detail.
