Error in EWB.

Cancell the E-Way bill and Prepare New One...

Yes you can cancel it ... generate fresh

cancellation time is over. it's three days old.

You should have notice the mistake before the movement of goods.

All you can do is intimate the department inform the department about the same indicating that the material was actually not sent and a credit note has now been issued against the invoice.... Though its not mentioned or required anywhere, its just a small procedure which you can follow to keep yourself on the safer side

Mail about it to Helpdesk also & keep the printout as record

Pankaj sir. In Invoice, the amount is correct. Then no need for credit note. Mistake was in Eway bill.
