Dear All,
Our actual invoice number is like AAA/001/17-18. when we file GSTR 1 we mistakenly mentioned invoice number like 001 alone. Prefix & suffix portions of the invoice numbers are missing. Our Service recipient notify us to rectify these errors by June 2020. Since amendment provision for FY 17-18 & 18-19 got over already we are unable to amend those invoices. Now my recipient sent us a debit note for the ITC amount. Kindly clarify will they really lose their ITC only because of a mismatch in prefix & suffix.
Note : Except this all details are matched ( like GSTIN, Date, Value, ITC)
