• What is the cause and solution for SAP error message /IBX/UIF005 - Constructor of application class &1 is PROTECTED ?

  The SAP error message /IBX/UIF005 Constructor of application class &1 is PROTECTED typically indicates that there is an attempt to instantiate a class whose constructor is declared as PROTECTED. In object-oriented programming, a PROTECTED constructor means that the class cannot be instantiated directly outside of its own class or its subclasses.
  Cause:
  
  Class Instantiation: The error occurs when there is an attempt to create an instance of a class that has a PROTECTED constructor. This usually happens when the class is designed to be a base class and is not meant to be instantiated directly.
  Incorrect Usage: The code may be incorrectly trying to instantiate a class that is intended to be subclassed, rather than using a subclass that has a public constructor.
  
  Solution:
  
  Use a Subclass: If you need to create an instance of the class, check if there is a subclass that has a public constructor. Instantiate the subclass instead of the base class.
  Modify the Class: If you have control over the class definition and it makes sense for your application, you could change the constructor from PROTECTED to PUBLIC. However, this should be done with caution, as it may violate the design principles of the class.
  Check Documentation: Review the documentation for the class to understand its intended use and find the correct way to instantiate or use it.
  Refactor Code: If the class is part of a framework or library, consider refactoring your code to align with the intended usage patterns of that framework.
  
  Related Information:
  
  Class Design: Understanding the principles of object-oriented design can help in recognizing when to use PROTECTED constructors and how to properly extend classes.
  SAP Documentation: Refer to SAP's official documentation or community forums for specific guidance related to the class in question.
  Debugging: Use debugging tools to trace where the instantiation is happening in your code, which can help identify the root cause of the error.
  
  By following these steps, you should be able to resolve the error and understand the underlying principles of class instantiation in SAP.
