• What is the cause and solution for SAP error message OO622 - Method & is abstract ?

  The SAP error message OO622, which states "Method & is abstract," typically occurs in the context of Object-Oriented ABAP programming. This error indicates that you are trying to call an abstract method that has not been implemented in a subclass. Abstract methods are defined in abstract classes and are meant to be overridden in derived classes.
  Cause:
  
  Abstract Method Call: You are attempting to call an abstract method directly from an instance of the abstract class or from a subclass that has not provided an implementation for that method.
  Missing Implementation: The subclass that is supposed to implement the abstract method has not done so, or the method is being called on the abstract class itself.
  
  Solution:
  
  
  Implement the Abstract Method: Ensure that any subclass of the abstract class implements the abstract method. You can do this by defining the method in the subclass with the same signature as in the abstract class.
  Example:
  CLASS my_subclass DEFINITION INHERITING FROM my_abstract_class.
    PUBLIC SECTION.
      METHODS my_abstract_method.
  ENDCLASS.
  
  CLASS my_subclass IMPLEMENTATION.
    METHOD my_abstract_method.
      " Implementation code here
    ENDMETHOD.
  ENDCLASS.
  
  
  Check Method Calls: Review the code where the method is being called. Ensure that you are calling the method on an instance of a concrete subclass that has implemented the method, not on the abstract class itself.
  
  
  Review Class Hierarchy: If you are working with multiple levels of inheritance, ensure that all subclasses in the hierarchy properly implement the abstract methods.
  
  
  Related Information:
  
  Abstract Classes and Methods: In ABAP, an abstract class is defined using the CLASS ... DEFINITION statement with the ABSTRACT keyword. Abstract methods are declared without an implementation and must be implemented in subclasses.
  Error Handling: When encountering this error, it is essential to check the stack trace or debug the program to identify where the abstract method is being called.
  Documentation: Refer to the SAP Help Portal or ABAP documentation for more details on object-oriented programming concepts, including abstract classes and methods.
  
  By following these steps, you should be able to resolve the OO622 error and ensure that your ABAP code adheres to the principles of object-oriented programming.
