• What is the cause and solution for SAP error message OL718 - The object type already has a method '&' ?

  The SAP error message OL718 indicates that there is an issue with the definition of a method in an object type. Specifically, it means that the object type you are working with already has a method defined with the same name as the one you are trying to create or modify. This can occur in the context of ABAP Object-Oriented programming when you are defining methods for classes or interfaces.
  Cause:
  
  Duplicate Method Name: You are attempting to create a method in a class or interface that already has a method with the same name.
  Inheritance: If the class is inheriting from a superclass that already has a method with the same name, this can also lead to this error.
  Typographical Error: Sometimes, a simple typo in the method name can lead to confusion, making it seem like you are trying to create a new method when you are not.
  
  Solution:
  
  Check Existing Methods: Review the existing methods in the class or interface to see if a method with the same name already exists. You can do this by navigating to the class or interface definition in the ABAP Workbench (SE80 or SE24).
  Rename the Method: If you find that the method already exists and you need to create a new one, consider renaming your new method to something unique.
  Override the Method: If you are trying to change the behavior of an existing method, you may want to override it instead of creating a new one. This can be done in a subclass if you are working with inheritance.
  Check for Inherited Methods: If your class is inheriting from a superclass, check the superclass for the method definition. You may need to override it in your subclass if that is your intention.
  Consult Documentation: If you are unsure about the method's purpose or how it is used, consult the SAP documentation or the existing codebase for guidance.
