• What is the cause and solution for SAP error message CM_ICI_CCS899 - Method '&1' has to be implemented by its subclasses ?

  The SAP error message CM_ICI_CCS899 indicates that a method (denoted as &1 in the message) is expected to be implemented by subclasses of a certain class in the context of the SAP system. This typically occurs in the context of object-oriented programming within SAP ABAP, where a method is defined in a superclass but is abstract or not implemented, and subclasses are expected to provide their own implementation.
  Cause:
  
  Abstract Method: The method in question is likely declared as an abstract method in the superclass. This means that it does not have an implementation in the superclass and must be implemented in any subclass that inherits from it.
  Missing Implementation: The subclass that is being used does not have an implementation for the required method, leading to this error when the method is called.
  Incorrect Class Usage: The class being instantiated or used may not be the correct subclass that should implement the method.
  
  Solution:
  
  
  Implement the Method: Check the subclass that is supposed to implement the method. You need to provide an implementation for the method in that subclass. This can be done by:
  
  Navigating to the subclass in the ABAP Workbench (SE80 or SE24).
  Implementing the method as required by the business logic.
  
  
  
  Check Class Hierarchy: Ensure that you are using the correct subclass. If you are instantiating a class that is not the intended subclass, you may need to change your code to use the correct one.
  
  
  Review Documentation: If available, review the documentation for the class and method to understand what the expected behavior is and how to implement it correctly.
  
  
  Debugging: If you are unsure where the error is occurring, you can use the ABAP debugger to trace the execution and see where the method call is being made.
  
  
  Related Information:
  
  ABAP Class and Method Documentation: Familiarize yourself with the ABAP class and method documentation to understand how to implement methods correctly.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any known issues or additional guidance related to this error message.
  Object-Oriented Programming in ABAP: If you are new to object-oriented programming in ABAP, consider reviewing resources or training materials that cover the basics of classes, inheritance, and method implementation.
  
  By following these steps, you should be able to resolve the error and implement the required method in the appropriate subclass.
