No purchase details in april to june gstr-4

Hello All,

In April to June 2018 GSTR-4 there was no need to show Purchases details in GSTR-4. And now in Jul to Sep 2018 GSTR-4 Return we need to show the same.

My query is that what about the purchases we made in April to June 2018. Is there any system where now we need to show the purchases made during that period April to June 2018?
