• What is the cause and solution for SAP error message /IBX/UIF026 - Constructor of application class &1 is PROTECTED ?

  The SAP error message /IBX/UIF026 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 from outside the class or its subclasses. This is a common design pattern used to control the instantiation of classes.
  Cause:
  
  Direct Instantiation: The error occurs when there is an attempt to create an instance of a class that has a PROTECTED constructor from outside the class or its subclasses.
  Incorrect Class Usage: The class might be intended to be used as a base class, and the developer is trying to instantiate it directly instead of using a derived class.
  
  Solution:
  
  Check Class Definition: Review the class definition of the application class mentioned in the error message. Ensure that you are not trying to instantiate it directly.
  Use Subclass: If the class is meant to be a base class, create a subclass that has a public constructor and instantiate that subclass instead.
  Factory Method: If applicable, use a factory method or a static method provided by the class to obtain an instance of the class.
  Review Documentation: Check the documentation or comments in the code to understand the intended usage of the class.
  
  Related Information:
  
  Object-Oriented Principles: Understanding the principles of encapsulation and inheritance in object-oriented programming can help clarify why certain constructors are protected.
  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 and ensure that the correct class is being used.
  
  If you continue to face issues, consider reaching out to your SAP support team or consulting with a developer who has experience with the specific application or module you are working with.
