• What is the cause and solution for SAP error message OO273 - Method &1 &2: Constructor method name is not 'CONSTRUCTOR' ?

  The SAP error message OO273 indicates that there is an issue with the constructor method of a class in ABAP Object-Oriented programming. Specifically, it states that the constructor method is not named 'CONSTRUCTOR', which is the required name for the constructor in ABAP classes.
  Cause:
  In ABAP, every class can have a constructor method that is automatically called when an instance of the class is created. The constructor method must be explicitly named CONSTRUCTOR. If you have defined a method intended to serve as a constructor but have named it something else, or if you have not defined a constructor at all, you will encounter this error.
  Solution:
  To resolve this error, you need to ensure that the constructor method is correctly defined. Here are the steps to fix the issue:
  
  
  Open the Class Definition: Go to the class where the error is occurring.
  
  
  Check the Method Name: Look for the method that is intended to be the constructor. Ensure that it is named CONSTRUCTOR.
  
  
  Define the Constructor: If the constructor is missing, you can define it as follows:
  CLASS your_class_name DEFINITION.
    PUBLIC SECTION.
      METHODS: CONSTRUCTOR.
  ENDCLASS.
  
  CLASS your_class_name IMPLEMENTATION.
    METHOD CONSTRUCTOR.
      " Initialization code here
    ENDMETHOD.
  ENDCLASS.
  
  
  Save and Activate: After making the necessary changes, save and activate the class.
  
  
  Test the Class: Create an instance of the class to ensure that the constructor is called without errors.
  
  
  Related Information:
  
  Constructor Method: In ABAP, the constructor method is used to initialize the object when it is created. It can take parameters to set initial values for attributes.
  ABAP Class Syntax: Familiarize yourself with the syntax for defining classes and methods in ABAP, especially the conventions for naming methods.
  Error Handling: If you encounter similar errors, check the method names and ensure they conform to the expected naming conventions in ABAP.
  
  By following these steps, you should be able to resolve the OO273 error and ensure that your class's constructor is properly defined.
