Arithmetic error - Intimation 143(1)(a)(i)

Must be some dis-allowance of exemptions claimed; check the order thoroughly.

Hello sir,

Even I got same intimation showing discrepancy in business income between ITR 3 and Computation as per intimation but when I'm comparing there's no such error in ITR 3 and calculation is rightly done by me.

How did you solve the problem?? 

Please help.

I filed revised return . Looks like some bug in I T Systems software .Particularly ITR 3
