  • What is the cause and solution for SAP error message TK028 - Cannot delete (request locks still exist) ?

    The SAP error message TK028 "Cannot delete (request locks still exist)" typically occurs when you attempt to delete a transport request in the SAP system, but there are still locks associated with that request. This can happen for various reasons, such as the request being in use, or it being locked by another user or process.

    Causes:

    1. Active Locks: The transport request is currently locked by another user or process, preventing deletion.
    2. Incomplete Transport: The transport request may not have been fully processed or released, leading to locks remaining.
    3. User Sessions: A user session may still be holding a lock on the transport request.
    4. Transport Management System (TMS) Issues: There may be issues with the TMS that are causing locks to persist.

    Solutions:

    1. Check Locks: Use transaction code SM12 to check for locks related to the transport request. You can filter by the transport request number and see if any locks are held by users.

      • If you find locks, you can either wait for the user to release them or, if appropriate, you can delete the locks yourself (ensure you have the necessary authorizations).
    2. Release the Transport Request: If the transport request is still in a "modification" state, ensure it is released properly using transaction code SE09 or SE10. Once released, you should be able to delete it.

    3. Check User Sessions: Use transaction code SM04 to check active user sessions. If you find a session that is holding a lock on the transport request, you can ask the user to log off or terminate the session if necessary.

    4. Transport Organizer: Go to the Transport Organizer (transaction SE09 or SE10) and check the status of the transport request. If it is in a "modification" state, you may need to release it before deletion.

    5. System Restart: In some cases, a system restart may help clear any lingering locks, but this should be done with caution and typically as a last resort.

    6. Consult Basis Team: If you are unable to resolve the issue, it may be necessary to consult your SAP Basis team for further assistance. They can help investigate deeper issues with the transport management system or database locks.

    Related Information:

    • Transaction Codes:
      • SE09 / SE10: Transport Organizer
      • SM12: Display and Delete Locks
      • SM04: User Sessions
    • SAP Notes: Check for any relevant SAP Notes that may address specific issues related to transport requests and locks.
    • Documentation: Review SAP documentation on transport management and locking mechanisms for a better understanding of how to manage transport requests effectively.

    By following these steps, you should be able to identify and resolve the issue causing the TK028 error message.
