11 June 2018  
I filed my GSTR 1 of jan18 wherein i mentiond wrong GSTN in one of the invoices which i want to correct now in GSTR1 of this month. When i go to the amendment section and enter the details of the invoice wrongly entered in jan'18, system is asking the details of revised invoice number. i filled the details of revised invoice number but still the system is asking the same.

pls guide what to do?
