Can i file revised return for ay 2015-16 (fy 2014-15)

I filed it on 18/08/2015 and recieved the Acknowledgement on 03/09/2015

Ok I think that could be tedious process.

The problem is my Housing Finance company issued an incorrect repayment certificate for FY 2014-15, missed to show 1 month's EMI. So, is there a way I can I deduct that interest in this year's (FY 2016-17's) return? or any other easier way?

Thanks for your reply!
