  Solutions:
  
  Check for Concurrent Users: Verify if another user is currently processing the same delivery. If so, wait for them to complete their task.
  System Monitoring: Use transaction codes like SM12 (to check for locks) and SM21 (to check system logs) to identify any locks or issues in the system.
  Database Administration: If there are database locks, consult with your database administrator to resolve them.
  Review Configuration: Check the configuration settings in EWM to ensure they are set up correctly for delivery processing.
  Retry the Operation: Sometimes, simply retrying the operation after a short period can resolve transient locking issues.
  Check for Background Jobs: Ensure that no background jobs are running that might be locking the delivery.
