• What is the cause and solution for SAP error message SHMM016 - This trace variant can only be used for methods of the superclass. ?

  The SAP error message SHMM016 indicates that a trace variant you are trying to use is not applicable for the method you are invoking because it is only valid for methods of the superclass. This typically occurs in the context of performance tracing or debugging in ABAP, particularly when dealing with class inheritance.
  Cause:
  
  Inheritance Issues: The trace variant you are using is defined for a superclass method, but you are trying to apply it to a subclass method that does not inherit the same tracing capabilities.
  Incorrect Trace Variant: The trace variant may not be correctly configured or may not be suitable for the specific method you are trying to trace.
  Method Visibility: The method you are trying to trace might not be visible or accessible in the context of the trace variant.
  
  Solution:
  
  Check Trace Variant Configuration: Review the configuration of the trace variant to ensure it is set up correctly for the methods you intend to trace. Make sure it is applicable to the subclass methods if that is your intention.
  Use the Correct Method: Ensure that you are invoking the correct method that corresponds to the trace variant. If the trace variant is meant for a superclass method, make sure you are tracing that specific method.
  Modify the Trace Variant: If necessary, modify the trace variant to include the subclass methods or create a new trace variant that is appropriate for the subclass.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on how to properly configure trace variants and understand their scope.
