• What is the cause and solution for SAP error message SCRL573 - 'CONSTRUCTOR' is not allowed as a method ID. ?

  The SAP error message SCRL573 indicates that there is an issue with the use of the keyword 'CONSTRUCTOR' in the context of method IDs in ABAP (Advanced Business Application Programming). This error typically arises when you are trying to define a method in a class or interface and incorrectly use 'CONSTRUCTOR' as a method ID.
  Cause:
  The error occurs because 'CONSTRUCTOR' is a special method in ABAP that is used to initialize an object of a class. It is not allowed to be used as a method ID in the same way as regular methods. The constructor method has a specific purpose and syntax, and it cannot be treated like a regular method.
  Solution:
  To resolve this error, you should ensure that you are using the 'CONSTRUCTOR' keyword correctly. Here are the steps to fix the issue:
  
  
  Check Method Definition: Ensure that you are not trying to define a method with the name 'CONSTRUCTOR'. Instead, you should define the constructor method using the correct syntax.
  CLASS your_class_name DEFINITION.
    PUBLIC SECTION.
      METHODS: constructor.
  ENDCLASS.
  
  CLASS your_class_name IMPLEMENTATION.
    METHOD constructor.
      " Initialization code here
    ENDMETHOD.
  ENDCLASS.
  
  
  Use Correct Syntax: If you are trying to define a constructor, make sure you are using the correct syntax as shown above. The constructor should not have a method ID like other methods.
  
  
  Review Class and Method Names: Ensure that there are no naming conflicts or typos in your class or method definitions.
  
  
  Check for Other Errors: Sometimes, this error can be a symptom of other issues in your code. Review the surrounding code for any other potential problems.
