Reusing an invoice number after IRN cancellation:
• After an IRN is cancelled (within 24 hours), the same invoice number can't be reused for a new IRN (the IRP rejects duplicate document numbers for the same GSTIN and FY). Issue a new invoice with a new number for the other party.
• In GSTR-1, the cancelled invoice is removed (auto-population deletes cancelled IRNs). Report the new invoice.
