• What is the cause and solution for SAP error message /BOBF/CONF159 - Class &1 inherits from obsolete library class &2 ?

  The SAP error message /BOBF/CONF159 Class &1 inherits from obsolete library class &2 indicates that a class in the Business Object Processing Framework (BOPF) is inheriting from a library class that has been marked as obsolete. This typically occurs when the underlying framework or libraries have been updated, and certain classes have been deprecated or replaced with newer versions.
  Cause:
  
  Obsolete Library Class: The class that your custom or standard class is inheriting from has been marked as obsolete in the SAP system. This can happen during system upgrades or when SAP deprecates certain functionalities.
  Custom Development: If you have custom classes that extend or use obsolete classes, this error may arise when the system checks for compatibility.
  
  Solution:
  
  Identify the Classes: Check the class definitions for both the class that is causing the error (&1) and the obsolete class (&2). You can do this using transaction SE24 (Class Builder).
  Update Inheritance: Modify the class definition of your custom class to inherit from a non-obsolete class. You may need to refer to the SAP documentation or release notes to find the recommended replacement class.
  Refactor Code: If your class relies on specific methods or properties of the obsolete class, you may need to refactor your code to accommodate the new class structure.
  Check for SAP Notes: Look for any relevant SAP Notes that may provide guidance on how to handle the transition from the obsolete class to the new class.
  Testing: After making the necessary changes, thoroughly test the functionality to ensure that everything works as expected.
