Here are the observations:

• Stock is visible in /SCWM/MON
• The product and quantity are available in the expected storage bin
• An outbound delivery order is created successfully
• Warehouse task creation fails, or the system shows that no stock is available for picking
• In some cases, the warehouse task is created with a partial quantity only
• No clear error message is displayed, or the error message is difficult to understand

I would like to understand the possible reasons why SAP EWM does not pick available stock.

Please help with the following points:

• How does SAP EWM determine stock availability during outbound picking?
• How do stock type, stock category, and availability group affect picking?
• Can a mismatch between ERP delivery stock type and EWM stock type prevent warehouse task creation?
• How do batch, party-entitled-to-dispose, owner, and special stock indicators affect stock selection?
• Can the storage type search sequence or stock removal rule cause this issue?
• How can we check whether stock is blocked, quality inspection stock, or assigned to another warehouse request?
• Which nodes in /SCWM/MON should be checked to identify the root cause?
• Which configuration settings should be verified for stock removal and outbound process type determination?
• What are the most common real-time project scenarios where stock exists but is not available for picking?

A step-by-step troubleshooting guide with relevant SAP EWM transactions, configuration paths, and a practical example would be very helpful.
