• What is the cause and solution for SAP error message /LTB/TR_UI061 - &1 is an interface and not an exception class ?

  The SAP error message /LTB/TR_UI061 &1 is an interface and not an exception class typically occurs in the context of ABAP programming, particularly when dealing with exception handling in the SAP system. This error indicates that the code is trying to use an interface as if it were an exception class, which is not allowed in ABAP.
  Cause:
  
  Incorrect Exception Handling: The error arises when an interface is mistakenly used in a context where an exception class is expected. In ABAP, exception classes must inherit from the base class CX_STATIC_CHECK or CX_DYNAMIC_CHECK, while interfaces do not have this inheritance.
  Code Misconfiguration: There may be a misconfiguration in the code where an interface is being referenced instead of a proper exception class.
  
  Solution:
  
  Check the Code: Review the code where the error occurs. Look for any RAISE statements or CATCH blocks that reference the interface instead of a valid exception class.
  Use the Correct Exception Class: Ensure that you are using a valid exception class. If you need to define a new exception, create a class that inherits from CX_STATIC_CHECK or CX_DYNAMIC_CHECK.
  Refactor the Code: If the interface is being used incorrectly, refactor the code to use the appropriate exception class. This may involve creating a new exception class if one does not already exist.
  Consult Documentation: Refer to the SAP documentation for exception handling in ABAP to ensure that you are following best practices.
  
  Related Information:
  
  ABAP Exception Handling: In ABAP, exceptions are used to handle errors and exceptional situations. They are defined as classes that inherit from specific base classes.
  Interfaces vs. Exception Classes: Understand the difference between interfaces and exception classes in ABAP. Interfaces define a contract for classes, while exception classes are specifically designed to handle errors.
  SAP Notes and Community: Check SAP Notes or the SAP Community for any known issues or additional guidance related to this error message.
  
  By following these steps, you should be able to resolve the error and ensure that your ABAP code handles exceptions correctly.
