• What is the cause and solution for SAP error message OO125 - You cannot change the visibility when you enter the type directly ?

  The SAP error message OO125, "You cannot change the visibility when you enter the type directly," typically occurs in the context of ABAP programming, particularly when dealing with object-oriented programming (OOP) in SAP. This error is related to the visibility of class components (attributes and methods) when you are defining a class or interface.
  Cause:
  The error arises when you attempt to change the visibility (public, protected, or private) of a class component while directly entering the type of that component. In ABAP, when you define a class or interface, you must specify the visibility of its components correctly. If you try to change the visibility of a component after specifying its type directly, the system will throw this error.
  Solution:
  To resolve this error, you should follow these steps:
  
  
  Check the Definition: Ensure that you are not trying to change the visibility of a component after you have already defined its type. The visibility should be defined before the type.
  
  
  Correct Syntax: Make sure you are using the correct syntax for defining class components. The visibility should be declared first, followed by the type. For example:
  CLASS my_class DEFINITION.
    PUBLIC SECTION.
      DATA: my_attribute TYPE my_type.
    PROTECTED SECTION.
      METHODS: my_method.
  ENDCLASS.
  
  
  Use the Correct Structure: If you need to define a component with a specific visibility, ensure that you are not mixing the visibility declaration with the type declaration. Always declare visibility first.
  
  
  Review Class/Interface Structure: If you are working with inherited classes or interfaces, ensure that you are not violating any visibility rules set by the parent class or interface.
  
  
  Related Information:
  
  
  Visibility Modifiers: In ABAP, there are three visibility modifiers:
  
  PUBLIC: Accessible from anywhere.
  PROTECTED: Accessible only within the class itself and its subclasses.
  PRIVATE: Accessible only within the class itself.
  
  
  
  ABAP Documentation: For more detailed information, refer to the official SAP documentation on ABAP Object-Oriented Programming, which provides guidelines on class definitions, visibility, and component declarations.
  
  
  Debugging: If you continue to face issues, consider using the ABAP debugger to step through your code and identify where the visibility is being incorrectly set.
  
  
  By following these guidelines, you should be able to resolve the OO125 error and correctly define the visibility of your class components in ABAP.
