• What is the cause and solution for SAP error message OO167 - Class constructors and destructors do not have parameters and exceptions ?

  The SAP error message OO167 indicates that there is an issue with the definition of class constructors and destructors in ABAP Object-Oriented programming. Specifically, this error arises when a class constructor or destructor is defined with parameters or exceptions, which is not allowed in ABAP.
  
  Cause:
  In ABAP, class constructors (CONSTRUCTOR) and destructors (DESTRUCTOR) are special methods that are automatically called when an instance of a class is created or destroyed. According to the ABAP language rules, these methods cannot take any parameters or raise exceptions. If you attempt to define a constructor or destructor with parameters or exceptions, you will encounter the OO167 error.
  
  Solution:
  To resolve the OO167 error, you need to modify the class definition by ensuring that the constructor and destructor do not have any parameters or exceptions. Here’s how you can do that:
  
  
  Remove Parameters: Ensure that the CONSTRUCTOR and DESTRUCTOR methods are defined without any parameters. For example:
  CLASS my_class
