• What is the cause and solution for SAP error message EU355 - Method &1 of the class &2 is not an instance method ?

  The SAP error message EU355 indicates that there is an issue with a method call in ABAP (Advanced Business Application Programming). Specifically, it means that the method you are trying to call is not defined as an instance method in the specified class. This can occur for a few reasons:
  Cause:
  
  Static Method Call: The method you are trying to call is defined as a static method in the class, but you are attempting to call it as if it were an instance method.
  Incorrect Method Name: There might be a typo in the method name or the class name, leading to the system not being able to find the correct method.
  Class Definition: The class might not be properly defined or might not be activated, leading to the method not being recognized.
  Inheritance Issues: If the method is inherited from a superclass, ensure that it is correctly defined in the subclass.
  
  Solution:
  
  
  Check Method Definition: Verify that the method you are trying to call is indeed defined as an instance method in the class. If it is a static method, you should call it using the class name instead of an instance.
  " Correct way to call a static method
  ClassName=>method_name( ).
  
  
  Correct Method Call: If the method is an instance method, ensure that you are calling it on an instance of the class:
  DATA: lo_instance TYPE REF TO ClassName.
  CREATE OBJECT lo_instance.
  lo_instance->method_name( ).
  
  
  Check for Typos: Double-check the spelling of the method and class names in your code to ensure there are no typographical errors.
  
  
  Activate Class: If you have recently made changes to the class or method, ensure that the class is activated in the ABAP Workbench.
  
  
  Review Inheritance: If the method is inherited, ensure that it is correctly defined in the parent class and that the subclass is properly set up to inherit it.
