like, at year start we have made a agreement with all are customers
that if purchase during the financial year exceeds 10 lacs a additional discount of 1% will be given on the purchased value during the invoice

And a buyer achieved the same 100 invoices transacted, now I need to give credit note how to link all 100 invoices and issue credit note along with gst reversal
