AFDs can be applied to Warp Cases, Data Cases, Compare cases, Data Rules (TestBench Advanced Edition only), Data sampling and File Effects in Results. In Warp Cases, Data Cases, Compare Cases and Data Rules availability of the AFD can be turned on or off with F17.

If an AFD is to be used, it must exist for the same file name as being worked on, either in the same specific library or a generic *LIBL (library list).
