Amended b2b invoices

Sir,

  Client Purchased Goods From Supplier in September 2018,That time Supplier not updated these invoice in Supplier's GSTR-1 in September 2018.

Now, Supplier  filed   September 2018  Invoices (ITC-1677.20) through Amended B2B Invoices in May 2019.

i have doubt in Receiver Tax Payer will get  (ITC-1677.20)  in May 2019 or Sep 2018.

Please give advice to us.
