When we conduct adverse impact analyses, we are comparing the number of people hired to the number of people who applied for the position. If a position is cancelled, there is no hire. If there is no hire, there are no applicants. Thus, the disposition should be changed to "job cancelled" for all people who applied to that position, whether they were considered for it or not.
