/IBX/UIF008 - Details

• The SAP error message /IBX/UIF008 Controller &1 is an abstract class typically indicates that the system is trying to instantiate or use a controller class that is defined as abstract. In object-oriented programming, an abstract class cannot be instantiated directly; it is meant to be subclassed, and its abstract methods must be implemented in a concrete subclass.
  
  Cause:
  
  Abstract Class Usage: The error occurs when the application attempts to create an instance of an abstract controller class instead of a concrete subclass that implements the necessary methods.
  
  Configuration Issues: There may be a misconfiguration in the application where the wrong class is being referenced.
  Development Errors: If you are developing or customizing the application, you might have mistakenly referenced an abstract class instead of a concrete implementation.
  
  
  Solution:
  
  Check Class Implementation: Ensure that you are using a concrete subclass of the abstract controller. Review the class hierarchy to find the appropriate subclass that should be instantiated.
