    <\/p>\n

    Q1. Difference between WM and EWM<\/h3>\n

    WM (classic LE-WM) offers basic bin-level control; EWM adds advanced capabilities: task\/WO orchestration, POSC\/LOSC, slotting, labor mgmt, yard, MFS, VAS, deconsolidation, embedded analytics.<\/p>\n

    Q2. EWM deployment options (basic vs advanced)<\/h3>\n

    Embedded EWM in S\/4HANA (Basic\/Advanced features via license) or Decentralized EWM on a separate system. Advanced adds labor mgmt, yard mgmt, MFS, slotting, etc.<\/p>\n

    Q3. EWM organizational structure<\/h3>\n

    ERP: Plant\/Storage Location \u2194 EWM: Warehouse Number \u2192 Storage Types \u2192 Storage Sections \u2192 Storage Bins. Add Activity Areas, Work Centers, and Dock Doors.<\/p>\n

    Q4. Storage types, sections, bins<\/h3>\n

    Storage type = logical zone (high rack, bulk, picking). Sections group bins by attributes (fast\/slow). Bin is the addressable location with bin type, capacity, and indicators.<\/p>\n

    Q5. Quant vs HU vs SU<\/h3>\n

    Quant = unique stock portion of same material\/batch in one bin. HU (handling unit) = physical load (pallet\/case) with SSCC. SU (WM) = storage unit; in EWM, HU supersedes SU.<\/p>\n

    Q6. Inbound process overview<\/h3>\n

    ERP PO\/IBD \u2192 EWM Inbound Delivery (IDO) \u2192 GR to goods receipt zone \u2192 deconsolidation\/quality \u2192 putaway tasks \u2192 final bin. Options: cross-docking, POSC, VAS.<\/p>\n

    Q7. Outbound process overview<\/h3>\n

    ERP SO\/ODO \u2192 EWM ODO \u2192 wave\/release \u2192 picking tasks \u2192 staging at doors\/work centers \u2192 packing\/label \u2192 PGI in EWM\/ERP \u2192 loading and ship.<\/p>\n

    Q8. Putaway strategies<\/h3>\n

    Fixed bin, next empty bin, addition to existing stock, near picking bin, weight\/volume-based, hazardous constraints, slotting-driven destination.<\/p>\n

    Q9. Picking strategies<\/h3>\n

    FIFO\/LIFO\/FEFO, partial picking from open HUs, pick-from-fixed bin, batch-based separation, multi-order picking, zone\/batch picking, pick & pass.<\/p>\n

    Q10. Warehouse tasks & orders<\/h3>\n

    WT = atomic move; WO groups WTs for execution by a resource. WO header carries execution parameters (queue, priority, limits).<\/p>\n

    Q11. WOCR (Warehouse Order Creation Rules)<\/h3>\n

    Rules to bundle WTs into WOs based on limits (weight\/volume\/qty), activity area, process type, and sort criteria for efficient routes.<\/p>\n

    Q12. POSC vs LOSC<\/h3>\n

    Process-Oriented Storage Control sequences mandatory steps (GR \u2192 Decon \u2192 Quality \u2192 Putaway). Layout-Oriented Storage Control reroutes by physical constraints (e.g., via elevator\/conveyor bins).<\/p>\n

    Q13. Work centers & deconsolidation<\/h3>\n

    Work centers execute packing\/decon\/quality\/VAS. Decon splits mixed HUs by destination\/storage type based on pack spec and POSC.<\/p>\n

    Q14. Packing specs & cartonization<\/h3>\n

    Pack specs define HU hierarchy, materials, and thresholds; Cartonization Planning suggests cartons\/HUs pre-pick. Shipping HUs get SSCC labels.<\/p>\n

    Q15. Waves & picking orchestration<\/h3>\n

    Waves group ODO items for synchronized picking by time, route, carrier, or door; templates control release methods and capacity constraints.<\/p>\n

    Q16. Slotting & rearrangement<\/h3>\n

    Calculates optimal bin\/storage type using velocity, dimensions, and packaging; rearrangement moves stock to new slots automatically or by proposal.<\/p>\n

    Q17. Replenishment types<\/h3>\n

    Planned (min\/max), order-related (pick demand), automatic during picking, and ad-hoc. Triggers WTs from reserve to pick-face bins.<\/p>\n

    Q18. Physical inventory procedures<\/h3>\n

    Annual, cycle counting, low stock check, zero stock check, and ad-hoc; supports HU\/bin\/inventory sampling with recount & difference posting.<\/p>\n

    Q19. Labor management basics<\/h3>\n

    Standards (engineered labor), performance measurement, and incentive pay support; requires engineered standards and activity capture.<\/p>\n

    Q20. Yard management (TU\/Vehicle)<\/h3>\n

    Manage yard bins, gates, check-in\/out, dock appointment scheduling; TU links deliveries to yard movements and doors.<\/p>\n

    Q21. Transportation units vs vehicles<\/h3>\n

    TU = logical load carrier (trailer\/container) with doors\/stops; Vehicle = tractor resource. TU can be moved\/parked\/assigned independently.<\/p>\n

    Q22. EWM-ERP integration objects<\/h3>\n

    Inbound\/outbound deliveries, stock transports, posting changes, production supply\/consumption, and status updates via qRFC.<\/p>\n

    Q23. qRFC\/CIF & Core Interface use<\/h3>\n

    qRFC ensures ordered, reliable messaging between ERP and EWM; CIF used for master data (materials, batches, classifications) and customizing.<\/p>\n

    Q24. Delivery types: ODO\/IDO<\/h3>\n

    Outbound Delivery Order (ODO) for shipping; Inbound Delivery (IDO) for receipts. They drive WT creation and document flow.<\/p>\n

    Q25. Warehouse process types (WPT)<\/h3>\n

    Define process behavior for tasks (putaway, picking, internal moves) incl. stock type changes, confirmation, exception handling, and queue.<\/p>\n

    Q26. Determination of WPT<\/h3>\n

    Based on process category, storage type, doc type, item type, packaging, and customizing (determination table & access sequence).<\/p>\n

    Q27. Availability groups & stock types<\/h3>\n

    Map EWM stock types (Available for Sale, QI, Blocked) to ERP special stocks. Availability group controls which stock is visible to which processes.<\/p>\n

    Q28. Quality integration (QM)<\/h3>\n

    Inspection at GR (01\/04), Q-holds in EWM, decision-driven stock postings; decon\/quality steps modeled in POSC.<\/p>\n

    Q29. Production integration (PMR\/Staging)<\/h3>\n

    PMR manages component staging to production supply areas (PSA), backflush consumption, and GI\/GR interface with PP.<\/p>\n

    Q30. Cross-docking types<\/h3>\n

    Opportunistic (direct from GR to GI), Planned cross-docking (PCD), and Flow-through via POSC; reduces storage and lead time.<\/p>\n

    Q31. VAS & kitting<\/h3>\n

    Value-Added Services (labeling, bundling) and kitting before\/after pick; integrated via work centers and pack specs.<\/p>\n

    Q32. RF framework & mobile<\/h3>\n

    Menu-driven RF screens for WT execution, scanning HUs\/bins, exception codes, and confirmations; supports Android and industrial terminals.<\/p>\n

    Q33. Exception codes & handling<\/h3>\n

    Operators use exception codes (e.g., short pick, bin blocked) to branch flows, trigger replenishment, or reassign tasks.<\/p>\n

    Q34. Queue & resource management<\/h3>\n

    Queues route WTs by area\/process; resources (forklifts, pickers) are assigned queues and activity areas; priorities & travel sequences optimize routing.<\/p>\n

    Q35. Sort sequences & consolidation groups<\/h3>\n

    Control pick path (Aisle\u2192Shelf\u2192Bin) and how items consolidate to HUs\/doors by route\/carrier\/shipping point.<\/p>\n

    Q36. MFS (Material Flow System)<\/h3>\n

    Direct PLC integration for conveyors\/ASRS with telegrams, routes, and bin connectivity; eliminates middleware for automation.<\/p>\n

    Q37. Batch & serial number handling<\/h3>\n

    Batch determination at pick\/putaway with characteristics; serial capture at HU\/item level; FEFO for shelf-life control.<\/p>\n

    Q38. Dangerous goods & hazmat<\/h3>\n

    Storage and transport checks for DG classes, segregation rules, labeling, and capacity constraints in storage types.<\/p>\n

    Q39. Value-added services vs pack spec<\/h3>\n

    VAS = operational tasks at work center; Pack spec = rules for HU creation & content. VAS can reference pack spec but also add non-pack tasks.<\/p>\n

    Q40. EWM Monitor essentials<\/h3>\n

    Central cockpit to manage WOs, WTs, stock, deliveries, exceptions, PI, and resources with drill-down and mass actions.<\/p>\n

    Q41. Inventory visibility & document flow<\/h3>\n

    Track from ERP PO\/SO \u2192 EWM IDO\/ODO \u2192 WTs\/WOs \u2192 HU\/bin stock; document flow ties logistics steps with timestamps & statuses.<\/p>\n

    Q42. Posting changes & stock transfers<\/h3>\n

    Intra-warehouse (bin-to-bin), inter-type (type-to-type), posting change (e.g., QI\u2192Unrestricted), and ERP 311\/313 mirrored by EWM tasks.<\/p>\n

    Q43. Performance tuning tips<\/h3>\n

    Use wave capacity groups, balanced WOCR, RF-directed picking, reduced POSC steps, queuing by zones, HU consolidation, and monitor-based exception cleanup.<\/p>\n

    Q44. Common master data pitfalls<\/h3>\n

    Missing pack specs, wrong dimens\/weight, incomplete slotting attributes, bin type\/capacity mismatches, incorrect availability group mapping.<\/p>\n

    Q45. Differences in S\/4HANA embedded EWM<\/h3>\n

    Tight FI\/CO\/PP\/QM integration, simplified master data, Fiori apps, advanced features via Business Functions; no separate middleware latency.<\/p>\n

    Q46. PPF actions in EWM<\/h3>\n

    Actions (labels, prints, IDoc\/XML) triggered by status\/events on deliveries\/HUs\/WOs; replace classic output determination.<\/p>\n

    Q47. Counting, recounting, zero stock check<\/h3>\n

    PI documents support initial count, tolerance-based recount, zero stock checks on empty bins, and difference posting to ERP\/EWM.<\/p>\n

    Q48. Best practices for EWM design<\/h3>\n
