You should take if your e-invoicing details need to be updated after cancelling an invoice:
Step 1: After generating the original e invoice, you cannot directly edit or make changes it because it has a unique E invoice Acknowledgment Number (Ack. No.), Acknowledgment Date (Ack Date), and INR number that have already been generated.
Step 2: If you need to make modifications to an e invoice or regenerate it with changes, you must cancel the original e invoice within 24 hours of its creation.
Step 3: After cancelling the original e invoice, you can then re generate a new e invoice with the necessary modifications. However, this new e invoice will have a different invoice number. It can't have the same number as the original e invoice.
By following these steps, you can effectively make changes to an e invoice that has already been created. Just remember that you need to cancel the original e invoice within the specified time frame, and the new invoice will have a different invoice number.
