GSTR-2A

If my vendor file his gstr-1, 3 months late let supposed he file his GSTR-1 of April month in July so which month can I get his all details in my GSTR-2A. I am already reconcile my GSTR-2A of April month which I get in may month and I didn't find my vendor invoice because he was not file gatr-1 but if he file his GSTR-1 in July of April month then I have to again generate file of gstr-2A of April month or not.
