• What is the cause and solution for SAP error message OO093 - Method &1 is not redefined ?

  The SAP error message OO093, which states "Method &1 is not redefined," typically occurs in the context of Object-Oriented ABAP programming. This error indicates that a method that is expected to be redefined in a subclass is not actually redefined, which can lead to issues in the inheritance hierarchy.
  Cause:
  
  Inheritance Issue: The method in question is defined in a superclass but has not been overridden in the subclass where it is being called.
  Abstract Method: If the method is declared as abstract in the superclass, it must be implemented in any subclass.
  Typographical Error: There may be a typo in the method name or signature in the subclass.
  Visibility: The method might be private in the superclass, making it inaccessible to the subclass.
  
  Solution:
  
  
  Redefine the Method: Ensure that the method is properly redefined in the subclass. You can do this by using the REDEFINITION keyword in the subclass method definition.
  CLASS subclass_name DEFINITION
    INHERITING FROM superclass_name
    FINAL
    CREATE PUBLIC.
  
  PUBLIC SECTION.
    METHODS: method_name REDEFINITION.
  ENDCLASS.
  
  
  Check Method Signature: Make sure that the method signature (parameters, return type) in the subclass matches that of the superclass.
  
  
  Implement Abstract Methods: If the method is abstract, ensure that you provide an implementation in the subclass.
  
  
  Check Access Modifiers: Verify the visibility of the method in the superclass. If it is private, consider changing it to protected or public if it needs to be accessed in the subclass.
  
  
  Review Inheritance Structure: Ensure that the class hierarchy is correctly set up and that the subclass is indeed inheriting from the correct superclass.
  
  
  Related Information:
  
  ABAP Documentation: Refer to the official SAP documentation for Object-Oriented ABAP to understand the principles of inheritance and method overriding.
  Debugging: Use the ABAP debugger to trace the execution and see where the method call is failing.
  Class Builder: Utilize the Class Builder (transaction SE24) to inspect the class definitions and method implementations.
  SAP Community: Engage with the SAP Community forums for additional insights and solutions from other developers who may have encountered similar issues.
  
  By following these steps, you should be able to resolve the OO093 error and ensure that your methods are correctly defined and redefined in your ABAP classes.
