• What is the cause and solution for SAP error message /SCWM/UI035 - Vehicle &1 is locked by user &2 ?

  The SAP error message /SCWM/UI035 Vehicle &1 is locked by user &2 typically occurs in the SAP Extended Warehouse Management (EWM) module when a vehicle (or transportation unit) is being accessed or modified by one user while another user attempts to access the same vehicle. This locking mechanism is in place to prevent data inconsistencies and ensure that only one user can make changes to a specific vehicle at a time.
  Cause:
  
  Concurrent Access: Another user is currently working on the same vehicle, which causes the system to lock it for other users.
  Session Timeout: A previous session may not have released the lock properly due to a timeout or unexpected termination.
  System Configuration: The system may be configured to lock vehicles for certain operations, and the current operation requires exclusive access.
  
  Solution:
  
  Wait and Retry: If the vehicle is locked by another user, the simplest solution is to wait until that user has completed their task and released the lock. You can then retry your operation.
  Identify the Locking User: If you have the necessary permissions, you can check which user is locking the vehicle. This can often be done through transaction codes like SM12 (to view locks) or SM21 (to view system logs).
  Contact the Locking User: If possible, communicate with the user who has the lock to understand their activity and see if they can release the lock.
  Release the Lock: If the locking user is no longer active (e.g., they have logged out or their session has crashed), a system administrator can manually release the lock using transaction SM12.
  Review System Configuration: If this issue occurs frequently, it may be worth reviewing the system configuration and user access patterns to optimize how locks are managed.
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with transaction codes like SM12 (to view and manage locks) and SM21 (to check system logs).
  User Training: Ensure that users are trained on how to properly release locks and manage their sessions to minimize locking issues.
  System Performance: Sometimes, performance issues can lead to locks not being released in a timely manner. Monitoring system performance may help identify underlying issues.
