• What is the cause and solution for SAP error message OO272 - Method &1 &2: Method is constructor, but not PUBLIC ?

  The SAP error message OO272 indicates that there is an issue with the visibility of a constructor method in an ABAP class. Specifically, the error states that the method is a constructor but is not declared as PUBLIC. In ABAP Object-Oriented Programming, constructors are special methods that are called when an instance of a class is created, and they need to be accessible to allow object instantiation.
  Cause:
  The error occurs when:
  
  A constructor method is defined in a class but is not declared with the PUBLIC visibility.
  The constructor is intended to be used outside of the class (e.g., when creating an instance of the class), but its visibility restricts access.
  
  Solution:
  To resolve this error, you need to change the visibility of the constructor method to PUBLIC. Here’s how you can do that:
  
  
  Open the Class Definition: Go to the class where the constructor is defined.
  
  
  Locate the Constructor Method: Find the method that is defined as the constructor (usually named CONSTRUCTOR).
  
  
  Change the Visibility: Ensure that the constructor is declared under the PUBLIC SECTION of the class definition. It should look something like this:
  CLASS my_class DEFINITION.
    PUBLIC SECTION.
      METHODS: constructor.
    PRIVATE SECTION.
      " Other methods and attributes
  ENDCLASS.
  
  CLASS my_class IMPLEMENTATION.
    METHOD constructor.
      " Constructor implementation
    ENDMETHOD.
  ENDCLASS.
  
  
  Activate the Changes: After making the changes, activate the class definition.
  
  
  Related Information:
  
  Constructor Method: In ABAP, the constructor method is a special method that is automatically called when an instance of the class is created. It is used to initialize the object.
  Visibility Sections: In ABAP classes, there are three visibility sections: PUBLIC, PROTECTED, and PRIVATE. The PUBLIC section allows access from outside the class, while PROTECTED and PRIVATE restrict access.
  Best Practices: Always ensure that constructors are declared as PUBLIC if you intend to create instances of the class from outside the class itself.
  
  By following these steps, you should be able to resolve the OO272 error and ensure that your constructor method is accessible for object instantiation.
