Itc as per gstr2a

INPUT AVAILED  ON BEHALF OF INVOICE ISSUED BY SUPPLIERS BUT SUPPLIER NOT FILED GSTR  1 AND WHAT TO DO

WE NEED TO REVESE THE INPUT OR WHAT PURCHASE MADE IN JULY 2017 BUT TILL NOVEMBER 2018 SUPPLIER NOT FILED GSTR1 AND DUE TO THAT IT IS NOT REFLACTING IN GSTR2A

AND SOME CASES SUPPLIER WRONGLY UPLOADED THE INVOICE ISSUED ON OUR GST NO UNDER B2CS COLOUM OF GSTR1 AND WE AVAILED INPUT 

PLEASE SUGGEST ON BOTH CASE 

 WE ARE ELIGIBLE TO AVAIL INPUT OR REVERSE THE SAME
