Inventory Management with SAP S4HANA (Bernd Roedel Johannes Esser) (z-library.sk, 1lib.sk, z-lib.sk)

【One-Line Pitch】 A practical, process-by-process guide to running inventory in SAP S/4HANA, from goods receipt through physical inventory and production execution. Best for SAP functional consultants, warehouse and materials planners, and key users who already know inventory concepts and now need the S/4HANA specifics. 【Book Arc】 - **Opening (~0%–10%)**: Sets the S/4HANA foundation—SAP HANA in-memory basics, the simplified data model (material documents in MATDOC, accounting documents in ACDOCA), functional changes, and the SAP Fiori user paradigm. Solves the "why is S/4HANA different from ECC?" question before any transaction work begins. - **Early (~10%–30%)**: Moves into configuration and planning—Implementation Guide structure, organizational units, inventory management and procurement settings, logistics execution, cross functions (date functions, responsibility management, situation handling, extensibility), then planning strategies, production master data, MRP Live, and DDMRP. - **Middle (~30%–60%)**: The transactional core—goods receipt via purchase order, inbound delivery, production order, and reference-free receipt; core inventory management including material document monitoring, stock identification, and physical inventory phases. - **Late (~60%–80%)**: Production execution—reservations, scheduling and manufacturing execution, production order monitoring and confirmation, goods receipt for production orders, scrap handling, and Kanban-driven replenishment. - **Ending (~80%–100%)**: The excerpts do not cover the closing chapters in detail; based on the table of contents, the book continues into advanced inventory topics and reporting beyond the production execution material shown here. 【Key Takeaways】 - **S/4HANA's simplified data model is the book's technical spine** (Opening): material documents consolidate into MATDOC and accounting documents into ACDOCA, which changes how you query and reconcile inventory data. Understanding this early makes later transaction chapters far easier. - **Configuration is treated as a first-class topic, not an afterthought** (Early): the Implementation Guide walkthrough covers organizational units, inventory management, procurement, logistics execution, and production planning settings, plus cross functions like situation handling and extensibility. - **Planning spans classic MRP and newer approaches** (Early): MRP Live, DDMRP with buffer profiles and replenishment execution, and Kanban control cycles are all covered, giving you a spectrum from traditional to demand-driven planning. - **Goods receipt is handled across multiple process variants** (Middle): purchase orders, inbound deliveries, production orders, and reference-free receipts, plus batch-managed materials, blocked stock, quality inspection, decentralized warehouse management, and return deliveries. - **Core inventory management centers on document visibility** (Middle): material document components, enterprise search, document flow analysis, and stock identification form the daily working toolkit. - **Physical inventory follows a clear phase model** (Middle): creating count documents, entering counts, processing results, and using the document overview—a repeatable cycle rather than a one-off task. - **Production execution connects planning to actuals** (Late): reservations, scheduling, work center monitoring, order confirmation, goods receipt for production orders, and scrap tracking (material scrap, operation scrap, scrap reason, excess consumption) close the loop. - **Kanban appears as both a planning and execution tool** (Late): control cycle management, JIT call scheduling, and Kanban calculation bridge replenishment planning with shop-floor execution. 【Reading Tips】 - **Deep-read the data model chapter first** (Opening): the MATDOC/ACDOCA shift explains why many ECC-era habits no longer apply; skimming it will make later chapters feel disconnected. - **Skim configuration if you are not a consultant**: the Implementation Guide and organizational unit sections are reference material—jump to the specific setting you need rather than reading linearly. - **Use the planning chapters as a decision guide**: compare MRP Live, DDMRP, and Kanban against your actual planning environment rather than treating them as sequential tutorials. - **Treat the transactional chapters as a workflow reference**: goods receipt, core inventory, and production execution are best consulted when you are executing a specific process, not read cover to cover. - **Watch for the "What's Ahead" sections**: they signal where SAP is heading (predictive MRP, for example) and help you prioritize what to learn next. 【Coverage Limits】 This guide is based on stratified excerpts covering roughly the first 60% of the book in detail, with the later chapters inferred from the table of contents. Specific configuration values, transaction codes, and the book's closing chapters are not fully represented in the source material.
