• What is the cause and solution for SAP error message OO613 - Constructors are not permitted in interfaces ?

  The SAP error message OO613 ("Constructors are not permitted in interfaces") occurs when you attempt to define a constructor method within an interface in ABAP (Advanced Business Application Programming). In ABAP, interfaces are meant to define a contract for classes, specifying methods that must be implemented, but they do not allow for the implementation of constructors or any other instance-specific behavior.
  
  Cause:
  The error is triggered when you try to declare a constructor method (using the CONSTRUCTOR keyword) inside an interface. Since interfaces are not meant to have any implementation details, including constructors, this is not allowed in ABAP.
  
  Solution:
  To resolve this error, you should remove the constructor definition from the interface. If you need to initialize certain values or perform setup tasks, consider the following alternatives:
  
  
  Use a Class Instead of an Interface: If you need a constructor, you might want to define a class instead of an interface. Classes can have constructors
