The delivery is available in SAP EWM, but the expected HU creation or automatic packing does not happen. In some cases, the warehouse task is created successfully, but the stock remains unpacked. In other cases, manual packing works, but automatic packing does not trigger.

Here are the observations:

• Inbound or outbound delivery is distributed successfully to SAP EWM
• Warehouse tasks may be created successfully
• No Handling Unit is created automatically
• Manual packing works in some cases
• Packaging material and product master data are maintained
• No clear error message is displayed, or the error message is difficult to understand

I would like to understand the possible reasons for this issue and how to troubleshoot it.

Please help with the following points:

• What configuration is required for automatic HU creation in SAP EWM?
• What is the role of packaging specifications in automatic packing?
• How do packing profiles and work centers affect HU creation?
• Which master data must be maintained for packaging material and products?
• Can warehouse process type or delivery item type affect automatic packing?
• How can we check whether the packaging specification is determined correctly?
• Which transaction codes and /SCWM/MON nodes should be checked?
• What are the common configuration mistakes that prevent automatic packing?
• How can automatic packing be tested for inbound and outbound delivery processes?

A step-by-step explanation with configuration paths, relevant transactions, and a real-time project example would be very helpful.
