The ExceptionType() function is the dedicated internal function in Blue Prism used to retrieve the classification of the current exception (e.g., "Business Exception", "Internal Exception", or "System Exception"). When an exception is caught by a Recover stage, this function becomes active and can be utilized within a Calculation stage to populate a data item. While ExceptionDetail() captures the specific error message text, ExceptionType() specifically extracts the category or "type" of the error, which is exactly what the "Save Exception Type" stage in your diagram is designed to do.
