it means we can show the sale invoices of 17-18. & same invoice ITC is available for purchase party in 17-18 only.
As in my case one- 17-18 invoice is pending in gstr1 of dec-17. due to that purchase party ask me for ITC amount with interest as it not showing in gstr2a of that party. if now we add that invoice in in dec-18 gstr1 return then it will clear the ITC issue to that party.
