What causes this issue?

There could not be found the suitably method source code for which the
method-exit (pre-/post-/overwrite-) should be added.
In case that the method redefinition is available<(>,<)> please check
your settings related to class builder:

• What is the cause and solution for SAP error message OO411 - PRE-/POST-/OWR-Exits can be created only for redefined methods ?

  The SAP error message OO411 indicates that there is an issue with the use of pre-exits, post-exits, or overwrite exits in the context of object-oriented programming in ABAP. Specifically, this error occurs when you attempt to create an exit for a method that is not a redefined method in a subclass.
  Cause:
  The error arises due to the following reasons:
  
  Non-redefined Method: You are trying to create an exit for a method that is not overridden in the subclass. Exits can only be defined for methods that have been redefined in the subclass.
  Incorrect Method Context: The method you are trying to apply the exit to may not be suitable for exits, such as static methods or methods that are not part of the inheritance hierarchy.
  
  Solution:
  To resolve the OO411 error, you can take the following steps:
  
  
  Check Method Redefinition:
  
  Ensure that the method you are trying to create an exit for is indeed redefined in the subclass. You can do this by checking the class definition and confirming that the method is marked as REDEFINITION.
  
  
  
  Use Correct Method:
  
  If the method is not intended to be redefined, consider whether you need to create an exit for a different method that is redefined.
  
  
  
  Review Class Hierarchy:
  
  Make sure that the class structure is correctly set up, and that the method you are trying to work with is part of the inheritance chain.
  
  
  
  Check for Static Methods:
  
  If you are trying to create an exit for a static method, remember that exits are not applicable to static methods. You will need to work with instance methods instead.
  
  
  
  Consult Documentation:
  
  Review the SAP documentation for object-oriented programming and exits to ensure you are following the correct procedures.
  
  
  
  Related Information:
  
  Exits in ABAP: Exits are a way to extend the functionality of methods without modifying the original code. They are particularly useful in enhancing standard SAP classes.
  Redefining Methods: In ABAP, a method can be redefined in a subclass to provide specific functionality. This is a key feature of polymorphism in object-oriented programming.
  SAP Notes and Community: If you continue to face issues, consider checking SAP Notes or the SAP Community for similar issues and solutions shared by other developers.
  
  By following these steps, you should be able to resolve the OO411 error and successfully create the necessary exits for your methods.
