Itr 4 revision

Hi.. I filed ITR 4 on 30/08/2016 for A.Y 2015-16. Now I have seen that a sum in Sec44AE was wrongly written in Sec44AD. So, to rectify this, will I have to revise my return or have to file another original return?? If revision, then what will b the receipt no in form ITR4? Plz reply asap. Thank you
