  The SAP error message /SCWM/POHU075 Item &1 of outbound delivery order &2 could not be locked typically occurs in the context of the Extended Warehouse Management (EWM) module when there is an issue with locking the item in an outbound delivery order. This can happen for several reasons, and understanding the cause is essential for finding a solution.
  Causes:
  
  Concurrency Issues: The item may be locked by another process or user. This can happen if multiple users or processes are trying to access or modify the same item simultaneously.
  System Performance: If the system is under heavy load, it may not be able to lock the item in a timely manner.
  Database Locking: There may be database-level locks that prevent the item from being locked in the application layer.
  Configuration Issues: Incorrect configuration in the EWM settings or in the outbound delivery process can lead to locking issues.
  Transport Issues: If the outbound delivery order is being processed in a different system (e.g., during a transport), it may not be accessible for locking.
  
  Solutions:
  
  Check for Active Sessions: Verify if another user or process is currently working on the same outbound delivery order. If so, wait for that process to complete.
  System Performance Monitoring: Monitor system performance and check for any bottlenecks. If the system is slow, consider optimizing performance or scheduling heavy processes during off-peak hours.
  Database Lock Monitoring: Use transaction codes like SM12 to check for any database locks that might be affecting the item. If you find locks that are no longer needed, you can release them (with caution).
  Review Configuration: Check the configuration settings in EWM related to outbound deliveries. Ensure that all settings are correct and aligned with business processes.
  Retry the Operation: Sometimes, simply retrying the operation after a short wait can resolve the issue if it was caused by a temporary lock.
  Check Logs: Review application logs for any additional error messages or warnings that might provide more context about the locking issue.
  Consult SAP Notes: Look for relevant SAP Notes that might address this specific error message or provide patches or updates that could resolve the issue.
