Invoice no. Change in e way bill

This discussion addresses the challenge of changing an invoice number on an e-way bill once the validity period has expired. Unfortunately, once an e-way bill is generated, it can only be cancelled within 24 hours. If a mistake is made, such as entering the wrong invoice number, and the 24-hour window has passed, there is no direct option to amend it. The advice given is to be careful with manual entries to avoid such issues in the future.
