• What is the cause and solution for SAP error message OZ114 - A lock method can only be used for lockable objects ?

  The SAP error message OZ114, which states "A lock method can only be used for lockable objects," typically occurs when there is an attempt to use a locking method on an object that is not designed to be locked. This can happen in various scenarios, particularly when dealing with database operations or when using SAP's locking mechanisms.
  Cause:
  
  Non-Lockable Object: The object you are trying to lock is not defined as a lockable object in the SAP system. This could be due to the object type or the way it has been defined in the system.
  Incorrect Locking Method: The method being used to lock the object may not be appropriate for the type of object you are working with.
  Programming Error: There may be a mistake in the ABAP code where the lock method is being called incorrectly or on the wrong object.
  
  Solution:
  
  Check Object Type: Ensure that the object you are trying to lock is indeed a lockable object. Review the documentation or the definition of the object to confirm its lockability.
  Use Correct Locking Method: Make sure you are using the appropriate locking method for the specific object type. For example, if you are working with database tables, ensure you are using the correct locking function (like ENQUEUE or DEQUEUE).
  Review ABAP Code: If you are a developer, review the ABAP code where the error occurs. Look for any discrepancies in how the lock method is being called. Ensure that the parameters being passed are correct and that the object is properly instantiated.
  Consult SAP Documentation: Refer to SAP's official documentation or help resources for guidance on the specific locking methods and their applicable objects.
  Debugging: If the issue persists, consider using the SAP debugger to trace the execution of the code and identify where the error is being triggered.
