• What is the cause and solution for SAP error message RTC_METHOD002 - Method &1 already exists. ?

  The SAP error message RTC_METHOD002, which states "Method &1 already exists," typically occurs in the context of the ABAP programming environment, particularly when working with classes and methods in the ABAP Workbench (SE80 or SE24). This error indicates that you are trying to create a method with a name that already exists in the specified class or interface.
  Cause:
  
  Duplicate Method Name: You are attempting to define a method with a name that is already used by another method in the same class or interface.
  Inheritance: If the class is inheriting from a parent class or implementing an interface, the method name might already exist in the parent class or interface.
  Typographical Error: There might be a typographical error in the method name you are trying to create, leading to confusion with an existing method.
  
  Solution:
  
  
  Check Existing Methods: Review the existing methods in the class or interface to see if the method name you are trying to create is already defined. You can do this by:
  
  Navigating to the class or interface in the ABAP Workbench (SE80 or SE24).
  Checking the list of methods to find any duplicates.
  
  
  
  Rename the Method: If you find that the method name is indeed already in use, consider renaming your new method to something unique that adheres to your naming conventions.
  
  
  Review Inheritance: If your class is inheriting from a parent class or implementing an interface, check those definitions to see if the method is defined there. If it is, you may need to override it instead of creating a new method.
  
  
  Use Method Overriding: If you intend to change the behavior of an existing method, you can override it in your subclass. Ensure that the method signature matches the one in the parent class.
  
  
  Consult Documentation: If you are unsure about naming conventions or method definitions, refer to your organization's coding standards or SAP documentation for guidance.
