Low amount of viable harvested fat - is this normal?

I recently had beautfill done to my entire abdomen, flanks, bra area, and lower back. They told me they suction 900cc out which I could see in one canister. I was supposed to have a BBL with the harvested fat. However, at the end of the procedure they told me the machine only gave them 60cc of viable fat. I was extremely disappointed because this ruined my chance for a BBL. Is it usual to have such a little amount of viable fat after this procedure?
