• What is the cause and solution for SAP error message OO253 - Attribute &1 &2: Attribute is only readable, but not PUBLIC ?

  The SAP error message OO253 indicates that you are trying to access an attribute that is defined as read-only and is not publicly accessible. This typically occurs in the context of ABAP Object-Oriented programming when you attempt to modify or access an attribute that is not intended to be changed directly from outside the class.
  Cause:
  
  Attribute Visibility: The attribute in question is defined with a visibility modifier (like PROTECTED or PRIVATE) that restricts access from outside the class or its subclasses.
  Read-Only Attribute: The attribute is marked as read-only, meaning it can only be set internally within the class and cannot be modified directly from outside the class.
  
  Solution:
  To resolve this error, you can consider the following approaches:
  
  
  Check Attribute Definition: Review the class definition to understand the visibility and mutability of the attribute. If you need to access or modify the attribute, you may need to:
  
  Change the visibility of the attribute to PUBLIC if appropriate.
  Ensure that you are using the correct methods provided by the class to access or modify the attribute.
  
  
  
  Use Getter/Setter Methods: If the attribute is intended to be read-only, you should use the provided getter method to access its value. If you need to modify it, check if there is a setter method available that allows you to change the value in a controlled manner.
  
  
  Refactor Code: If you are trying to access the attribute directly, refactor your code to use the class's public interface (methods) instead of accessing the attribute directly.
  
  
  Related Information:
  
  ABAP Object-Oriented Programming: Understanding the principles of encapsulation, visibility, and access control in ABAP OO is crucial. Attributes should be accessed through methods to maintain the integrity of the class.
  Documentation: Refer to the SAP documentation for more details on object-oriented programming in ABAP, including best practices for defining and using attributes and methods.
  Debugging: If you are unsure where the error is occurring, use the ABAP debugger to trace the execution and identify the point where the error is triggered.
  
  By following these steps, you should be able to resolve the OO253 error and ensure that your code adheres to the principles of object-oriented programming in ABAP.
