Field conversions control how data is displayed to the user. All fields have a default conversion, which you can override in certain instances, such as in Reporting.
For example, the default conversion for the Classification file is AU_ASCENDING. This means that when terms are displayed in Classification fields and in reports, the user will see the ascending hierarchy, e.g. Dish, Bonbon/Dish, Candy/Dish, Serving/Serving Vessels/Food Service T&E/04 Tools. You may wish to override this in a report so that just the term name displays, e.g. just Dish, Bonbon.
