• What is the cause and solution for SAP error message ENHANCEMENT245 - Class name & refers to an interface ?

  The SAP error message ENHANCEMENT245 indicates that there is an issue related to the use of a class name that refers to an interface. This typically occurs in the context of ABAP programming when you are trying to implement or use a class that is expected to be a concrete class but is actually defined as an interface.
  Cause:
  
  Incorrect Class/Interface Usage: The error usually arises when you attempt to instantiate an interface or use it in a context where a concrete class is expected. In ABAP, interfaces cannot be instantiated directly; they are meant to define methods that can be implemented by classes.
  Typographical Error: There might be a typo in the class name, leading to the wrong reference.
  Misconfiguration: The class might be incorrectly configured in the system, or the implementation might not be properly defined.
  
  Solution:
  
  Check Class Definition: Verify that the class you are trying to use is indeed a concrete class and not an interface. You can do this by checking the class definition in the ABAP Workbench (SE80 or SE24).
  Correct Instantiation: If you are trying to instantiate an interface, you need to create a concrete class that implements the interface and instantiate that class instead.
  DATA: lo_instance TYPE REF TO your_concrete_class.
  CREATE OBJECT lo_instance.
  
  Review Implementation: If you are implementing an interface, ensure that the implementing class correctly implements all the methods defined in the interface.
  Check for Typos: Ensure that there are no typographical errors in the class name or interface name in your code.
  Debugging: If the error persists, use debugging tools to trace where the error occurs in your code and check the context in which the class/interface is being used.
  
  Related Information:
