SAP EWM Outbound Process

You are an SAP EWM (Extended Warehouse Management) specialist. The user wants to process outbound deliveries efficiently using wave management and packing operations.

What to check first

• Verify SAP EWM module is active: Check transaction SPRO > SAP Customizing > Logistics - Execution > Extended Warehouse Management > master data exists
• Run /SAPAPO/CWLC to ensure Wave and Packing configuration is enabled in your system
• Check user authorization for transactions LY21 (Outbound Delivery Monitor) and /SAPAPO/OB02 (Wave Creation)

Steps

1. Create or retrieve outbound delivery in LY21 (Outbound Delivery Monitor) or check existing deliveries in the system
2. Execute transaction /SAPAPO/OB02 (Wave Creation Wizard) to group deliveries into waves based on shipping point, route, or delivery priority
3. Confirm wave in /SAPAPO/OB03 (Wave Overview) and execute wave processing to trigger picking work creation
4. Navigate to LY50 (Packing) and select the outbound delivery line items requiring packing
5. In the packing screen, enter packing material/container type using field VERP_MAT and configure hazmat/weight limits if applicable
6. Execute packing process to generate pack/handling units (HUs) with track/trace barcodes in HUMO view
7. Confirm all line items are packed and generate shipping notification via LY80 (Shipping Notification) or integrate via ORDERS05 IDOC outbound
8. Post goods issue in VL02N to deduct inventory and trigger billing document creation downstream

Common Pitfalls

• Treating this skill as a one-shot solution — most workflows need iteration and verification
• Skipping the verification steps — you don't know it worked until you measure
• Applying this skill without understanding the underlying problem — read the related docs first

When NOT to Use This Skill

• When a simpler manual approach would take less than 10 minutes
• On critical production systems without testing in staging first
• When you don't have permission or authorization to make these changes

How to Verify It Worked

• Run the verification steps documented above
• Compare the output against your expected baseline
• Check logs for any warnings or errors — silent failures are the worst kind

Production Considerations

• Test in staging before deploying to production
• Have a rollback plan — every change should be reversible
• Monitor the affected systems for at least 24 hours after the change
