• What is the cause and solution for SAP error message /PM0/3FP_MESSAGES000 - Method &1 was not redefined ?

  The SAP error message /PM0/3FP_MESSAGES000 Method &1 was not redefined typically occurs in the context of ABAP programming, particularly when dealing with class methods in Object-Oriented Programming (OOP) within SAP.
  Cause:
  This error indicates that a method (denoted by &1 in the message) is expected to be redefined in a subclass but has not been implemented. In SAP ABAP, when you create a subclass that inherits from a superclass, you may override methods from the superclass. If you attempt to call a method that is supposed to be redefined in the subclass but is not, this error will be triggered.
  Solution:
  To resolve this error, you should:
  
  
  Check the Class Hierarchy: Verify the class hierarchy to ensure that the method in question is indeed intended to be redefined in the subclass.
  
  
  Implement the Method: If the method is supposed to be redefined, implement it in the subclass. You can do this by:
  
  Navigating to the subclass in the ABAP Workbench (SE80 or SE24).
  Finding the method in the method list.
  Implementing the method logic as required.
  
  
  
  Check Method Signature: Ensure that the method signature (parameters, return type, etc.) in the subclass matches that of the superclass. Any discrepancies can lead to issues.
  
  
  Activate the Class: After implementing the method, make sure to activate the class to ensure that the changes take effect.
  
  
  Test the Implementation: After making the changes, test the functionality to ensure that the error no longer occurs and that the method behaves as expected.
  
  
  Related Information:
  
  ABAP Class and Method Documentation: Familiarize yourself with the ABAP Object-Oriented Programming concepts, especially regarding class inheritance and method overriding.
  Debugging: If you are unsure where the error is occurring, you can use the ABAP debugger to trace the execution and identify where the method call is made.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any known issues or additional guidance related to this error message.
  
  By following these steps, you should be able to resolve the error and ensure that your ABAP classes function correctly.
