Basic SAP SCM-PP-EWM Process

This process flow will help you to understand basic SCM-PP-EWM process flow from business point of view.

Pre-requisites:

• All Production Planning master data (Material Master, BOM, Work Centre, Routing and Production Versions) are maintained correctly.
• All EWM master data are maintained correctly, like (Product Master /SCWM/MAT1, Controle Cycle LPK1 etc.)

Planning Process (Production Planner)

1. Business enters forecast (MD61) or with any mass upload tool.
2. Verify uploaded forecast (MD63) or directly in Stock Req. List (MD04).
3. Execute MRP run (MD02) or MRP Live (MD01N).
4. After MRP, for in-house (E) produced part system generates Planned Orders. Business can verify it in MD04 or Production Order Information System (COOIS).
5. Perform ATP for planned order (MDVP) and Capacity Planning (CM01/CM21).
6. Convert Planned Order to Production Order (CO40/CO41) or directly from Stock Req. List (MD04).
7. Release Production Order (CO02) or Mass Release (CO05N), after release and save, system performs printing, PMR for EWM etc.

SCM-EWM Process (Warehouse Manager & Warehouse Operator)

1. Once, production order is released, system generated Production Material Request (PMR) for EWM system, warehouse business verifies the PMR with transaction /SCWM/PMR.
2. Against the PMR, business performs material staging with transaction /SCWM/STAGE, which generates warehouse task in EWM.
3. Once business, confirms these warehouse task (/SCWM/MON), requested components are staged at PSA maintained in the Production Work Centre.

Production Process (Production Supervisor & Production Operator)

1. Production user performs order confirmation (CO15 or CO11N).
2. If Backflush is enabled for components, system automatically posts GI (261) while performing CO11N, else business posts GI manually via MIGO.
3. Once GI is posted from ERP, an outbound delivery (OBD) gets created in ERP and it gets distributed in EWM system.
4. If auto-GR is enabled, system automatically posts Goods Receipt (101) at the order confirmation (CO15/CO11N), else business posts GR manually via MIGO.

PP-EWM Process (Warehouse Manager & Warehouse Operator)

1. Once, outbound delivery is distributed to EWM system, business process the outbound delivery via /SCWM/PRDO or directly in Warehouse Monitor /SCWM/MON.
2. Once, inbound delivery is distributed to EWM system, business process the inbound delivery via /SCWM/PRDI or directly in Warehouse Monitor /SCWM/MON.
3. In case any error occurs during processing of GI/GR from EWM system, it gets captured in EWM Queues (Transaction SMQ2), business can access is directly from Warehouse Monitor /SCWM/MON.
4. Upon successful posting of GI/GR from EWM system, corresponding Inbound or Outbound Delivery gets completed in ERP system and material document posted in ERP system for the same.

Production Process (Production Supervisor & Production Operator) - TECO

1. Upon successful confirmation of orders, business verifies that all the operations are confirmed correctly and GI/GR posted via Production Order Information System (COOIS).
2. Now, Production orders are marked technically closed (TECO), via transaction CO02 or mass processing tool COHV.
