Local purchase return in karnataka

Sir,

We made one purchase on 31.12.2015 and rejected in 13.01.2016 and raised debit note. In December month we have taken input credit. Since the item is rejected and returned back, I want to know the rejection amount whether that should be entered in 9.12.1 coloum sepeately or we can deduct the same from total loca purchases. 

Please reply

with regards
