Intimation u\s 143(1) due to dep. shedule left blank

I have filled return of my client on 20.06.10 claiming dep. in p& l a\c but i leave blank dep. shedule.

Now i got an intimation u\s 143(1) in which income has been increased by amount of dep. and claiming tax demand to be deposit.

Now what should i do??

My own comment:- Now i have two remedies i can file revise return 139(5) or rectification petition 154.

Q1. If i file revise return then next intimation 143(1) will show demand nil but if demand has become enforceable u/s 156(143(1)) then can we nullify the effect by filling revise return.

Q2.If i go for 154 then ito, delhi office or to banglore online

OR I SHOULD DO BOTH

Please tell me

Thanx
