• What is the cause and solution for SAP error message TK164 - Internal error: Request &1 is locked; action canceled ?

  The SAP error message TK164 indicates that a request is locked, which prevents further actions from being taken on that request. This can occur in various scenarios, such as during transport management or when working with change requests in the SAP system.
  Cause:
  
  
  Locked Request: The request you are trying to process is currently locked by another user or process. This can happen if:
  
  Another user is editing the request.
  The request is in a state that requires it to be locked (e.g., being released or imported).
  There was an unexpected termination of a process that left the request in a locked state.
  
  
  
  Transport Management Issues: If the request is part of a transport, it may be locked due to transport management activities.
  
  
  Database Locks: Sometimes, database locks can cause requests to appear as locked.
  
  
  Solution:
  
  
  Check Lock Entries:
  
  Use transaction code SM12 to check for lock entries. You can filter by the user or the request number to see if there are any active locks.
  If you find a lock that is no longer needed, you can delete it (if you have the necessary authorizations).
  
  
  
  Release the Lock:
  
  If the lock is held by another user, communicate with that user to see if they can release the request.
  If the lock is due to a process that has failed, you may need to terminate that process.
  
  
  
  Transport Organizer:
  
  If the request is part of a transport, check the transport organizer (transaction code SE09 or SE10) to see if there are any issues with the transport.
  
  
  
  System Restart:
  
  In some cases, a system restart may be necessary to clear any lingering locks, especially if they are due to a system error.
  
  
  
  Check for Background Jobs:
  
  Sometimes, background jobs may hold locks. Use transaction code SM37 to check for any background jobs that might be related to the request.
  
  
  
  Related Information:
  
  Authorization: Ensure you have the necessary authorizations to view and delete locks.
  Transport Management System (TMS): Familiarize yourself with TMS if the issue is related to transport requests.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message. You can search for the error message number in the SAP Support Portal.
  
  If the issue persists after trying the above solutions, it may be necessary to consult with your SAP Basis team or SAP support for further assistance.
