  The SAP error message /SAPAPO/MC01031 Class & cannot be deleted, see where-used list typically occurs in the SAP Advanced Planning and Optimization (APO) module when you attempt to delete a class (such as a characteristic class) that is still being used in the system. This error indicates that the class you are trying to delete is still referenced in other objects, and therefore, cannot be removed until those references are cleared.
  Cause:
  
  Active References: The class you are trying to delete is still being used by other objects, such as characteristics, planning objects, or other classes.
  Dependencies: There may be dependencies in the system that prevent the deletion of the class.
  Configuration: The class may be part of a configuration that is still active or in use.
  
  Solution:
  
  
  Check Where-Used List: 
  
  Use the "Where-Used List" functionality in SAP to identify all the objects that are using the class. You can do this by navigating to the class in the SAP GUI and using the "Where-Used List" option (usually found in the menu).
  This will show you all the characteristics, planning objects, or other classes that reference the class you want to delete.
  
  
  
  Remove References:
  
  Once you have identified the objects that are using the class, you will need to either delete or modify those objects to remove the references to the class.
  Ensure that any dependent objects are no longer using the class before attempting to delete it again.
  
  
  
  Check for Active Configurations:
  
  If the class is part of an active configuration, you may need to deactivate or delete that configuration first.
  
  
  
  Consult Documentation: 
  
  Review SAP documentation or consult with your SAP Basis or APO consultant for specific steps related to your system configuration.
  
  
  
  Authorization: 
  
  Ensure that you have the necessary authorizations to delete classes and make changes in the APO module.
