• What is the cause and solution for SAP error message FOX0084 - Profile extension &1: Class &2 does not inherit from class &3 ?

  The SAP error message FOX0084 indicates that there is an issue with the profile extension in the context of the SAP system's authorization management. Specifically, it means that the class specified in the error message does not inherit from the expected base class. This can occur in various scenarios, such as when working with authorization profiles, roles, or custom classes.
  Cause:
  
  Incorrect Class Definition: The class specified in the error message (&2) does not extend or inherit from the required base class (&3). This could be due to a misconfiguration or an error in the class definition.
  Profile Extension Issues: The profile extension being attempted is not valid because the class hierarchy is not correctly set up.
  Transport Issues: If the class was transported from another system, it may not have been transported correctly, leading to inconsistencies.
  
  Solution:
  
  
  Check Class Hierarchy: Verify that the class specified in the error message (&2) is correctly defined and that it inherits from the expected base class (&3). You can do this by navigating to the class in the ABAP Workbench (transaction SE80 or SE24) and checking its inheritance.
  
  
  Correct Class Definition: If the class does not inherit from the required base class, you may need to modify the class definition to ensure it does. This may involve changing the class declaration or creating a new class that correctly inherits from the base class.
  
  
  Review Profile Configuration: Check the configuration of the profile extension to ensure that it is set up correctly and that all necessary classes are included.
  
  
  Transport Check: If the issue arose after a transport, check the transport logs and ensure that all necessary objects were included in the transport request. You may need to re-transport the class or related objects.
  
  
  Consult Documentation: Review SAP documentation or notes related to the specific classes and profiles you are working with to ensure compliance with best practices.
  
  
  Testing: After making the necessary changes, test the profile extension again to ensure that the error is resolved.
