• What is the cause and solution for SAP error message LTRM041 - Object class has a parent class; leave ALV Structure field blank ?

  The SAP error message LTRM041 indicates that there is an issue with the configuration of an ALV (ABAP List Viewer) structure in the context of the Logistics Execution (LE) module, specifically related to the object class hierarchy. The message suggests that the object class you are trying to define has a parent class, and therefore, the ALV structure field should be left blank.
  Cause:
  The error occurs when you attempt to create or modify an object class in the SAP system that already has a parent class defined. In the context of ALV structures, the system expects that if an object class has a parent, the ALV structure field should not be populated, as it is typically inherited from the parent class.
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check Object Class Hierarchy:
  
  Verify the object class you are working with and its parent class. You can do this by navigating to the relevant configuration or customizing transaction in SAP.
  
  
  
  Leave ALV Structure Field Blank:
  
  If the object class has a parent class, ensure that the ALV Structure field is left blank. This means you should not enter any value in the ALV Structure field for this specific object class.
  
  
  
  Save Changes:
  
  After making the necessary adjustments, save your changes and check if the error persists.
