The JSON and Excel formats for consolidated debit or credit notes are not available on the department portal. If you are using TallyPrime for filing returns, you need to link a debit or credit note against only one corresponding original invoice. If you are using TallyPrime only to record transactions and not for filing returns, you can record the debit or credit notes against multiple original invoices. While filing returns on the portal, you can manually enter the details of multiple original invoices against which the debit or credit notes were recorded.
