Hi Anitha,
Instead of letting Adobe do all the heavy lifting if you only care to track the final abandonment step (if any). You should set a session base "form-abd" cookie or local storage as Jan suggested in the article on each form step i.e. _satellite.cookie.set(). You can actually overwrite the previous step name in "form-abd" cookie with subsequent step name with user progression (use s.tl rules to do this). when user submits form deletes "form-abd" cookie i.e. _satellite.cookie.remove(), if user abandonment from any step read "form-abd" cookie on next page or exit; set in an (eVar/prop) and then delete "form-abd" cookie to avoid multiple read instances.
This way you can get only the steps where the user is abandoning most. Lmk if you have questions.
Thanks,
Asheesh
