Is there a way to turn off the warning for duplicate sales receipt numbers?

Hello @louisvilleapa,

At this time, there isn't an option to turn off the warning for an existing transaction number when creating a sales receipt or any sales transaction.

This way, you can avoid creating a duplicate copy of your transactions that might mess up the balance of your account.

Keep me posted in the comment section down below if you have any other questions. I'm always around happy to help.
