In Auto Drafted July 2017 GSTR2A I have received one bill GST credit short fall amount of CGST Rs,150 and SGST Rs.150. Since I have filed July2017 GSTR3B by availing the correct GST credit as per bill issued by Party's in July2017. My question is whether I have to reject this bill and Add as missing bill by correcting CGST and SGST amount. If I accept this bill it will burden on me for short payment of CGST Rs.150 and SGST Rs.150. Please Reply.
