  • What is the cause and solution for SAP error message WRF_APC243 - Purchasing list item &1 &2 is locked by user &3 ?

    Certainly! Here's a detailed explanation of the SAP error message:


    SAP Error Message:

    WRF_APC243 Purchasing list item &1 &2 is locked by user &3


    Meaning / Cause:

    This error occurs when you try to edit or process a purchasing list item (such as a purchase requisition or purchase order item) that is currently locked by another user. SAP uses lock entries to prevent simultaneous changes to the same data by multiple users, ensuring data consistency and avoiding conflicts.

    • &1 = Document number (e.g., purchase requisition or purchase order number)
    • &2 = Item number within the document
    • &3 = User ID who currently holds the lock

    The message indicates that the item you want to work on is locked by another user, so you cannot make changes until the lock is released.


    Typical Causes:

    • Another user is currently editing the purchasing list item.
    • A previous session/user did not release the lock properly (e.g., session ended abnormally).
    • Background jobs or workflows are processing the item.
    • Lock entries were not cleared due to system issues.

    Solution / How to Resolve:

    1. Check who holds the lock:
      Identify the user (&3) who currently has the lock. You can contact that user to finish their work and release the lock.

    2. Wait and retry:
      If the lock is temporary (e.g., user is actively working), wait until the user finishes and the lock is released.

    3. Use transaction SM12 to monitor and delete locks:

      • Go to transaction SM12 (Lock Entries).
      • Enter the relevant object or user name to find the lock entry.
      • Verify if the lock is still valid or if it is a stale lock (e.g., user session ended).
      • If confirmed that the lock is stale and safe to remove, delete the lock entry.
        Note: Deleting locks should be done carefully and usually by a system administrator or with proper authorization.
    4. Check for background jobs or workflows:
      Sometimes background processes or workflows hold locks. Check if any jobs are running that might be locking the item.

    5. System restart or user session termination:
      If locks persist due to system issues, a system restart or terminating user sessions might be necessary.


    Related Information:

    • Lock objects related to purchasing documents include EKKO (purchase order header), EKPO (purchase order item), EBAN (purchase requisition), etc.
    • Lock entries are managed by SAP lock mechanism to ensure data integrity.
    • Frequent lock conflicts may indicate process or system performance issues.
    • For custom developments, ensure proper lock handling using ENQUEUE and DEQUEUE function modules.

    Summary:

    Aspect Details
    Error Purchasing list item is locked by user
    Cause Item is currently locked by another user
    Solution Contact user, wait, or delete lock via SM12
    Transaction SM12 (Lock Entries)
