What happens when I purge ABC information?
You purge an ABC group to delete all item assignments to ABC classes for the assignment group, as well as the ABC group itself. Purging an ABC classification set deletes all item values and ranking for the ABC classification set you specify, as well as the ABC classification set itself.
Note: You cannot purge ABC information that is being used;
for example, an ABC classification set is not purged if it is associated
to an ABC assignment group.
