Smart SAP Assistant

• What is the cause and solution for SAP error message OO164 - Method &1 is final and therefore cannot be redefined ?

  The SAP error message OO164 indicates that you are trying to redefine a method in an ABAP class that has been declared as "final." In object-oriented programming within ABAP, a method marked as final cannot be overridden in subclasses. This is a design choice to prevent changes to critical methods that should maintain their original behavior.
  Cause:
  The error occurs when:
  
  You attempt to redefine a method in a subclass that has been declared as final in the superclass.
  The method in the superclass is defined with the FINAL keyword.
  
  Solution:
  To resolve this error, you have a few options:
  
  
  Do Not Redefine the Method: If the method is final, you cannot redefine it. You should use the method as it is defined in the superclass without attempting to override it.
  
  
  Check Class Design: If you believe that the method should be redefined, you may need to reconsider the design of your classes. You can:
  
  Remove the FINAL keyword from the method in the superclass if you have control over that class and if it makes sense to allow overriding.
  Create a new method in the subclass with a different name if you need additional functionality.
  
  
  
  Use Composition Instead of Inheritance: If you need different behavior, consider using composition instead of inheritance. This allows you to use instances of the superclass within your subclass without needing to override methods.
  
  
  Related Information:
  
  Final Methods: In ABAP, a method can be declared as final using the FINAL keyword in its definition. This is often done to ensure that the method's implementation remains unchanged in subclasses.
  Inheritance in ABAP: Understanding how inheritance works in ABAP is crucial. When designing classes, consider which methods should be final and which should be open for overriding.
  Documentation: Refer to the official SAP documentation on ABAP Object-Oriented Programming for more details on class design, method definitions, and best practices.
  
  By following these guidelines, you should be able to address the OO164 error effectively.
