Rectification u/s 154

I have received intimation u/s 143(1)for a.y.2010-11 in which demand of Rs.638 has been raised due current year loss of normal business(Rs. 91128) was not allowed as set off to extent of speculation profit(Rs.2168) in reply of which i have filed rectification request to CPC. after sometime i have received order u/s 154 for claiming the same demand as mentioned in above metter.

 what further action can i take? should i take the help of local IT officer? is there any online process?
