Discard an Existing Checkout
Discarding an existing checkout can be helpful for when you started a checkout by accident, or you need to make any changes to the ticket after you've started the checkout.
Open the appointment with the checkout that should be discarded on the calendar
In the sidebar, click "Continue" to bring up the existing checkout.
In the "..." menu select "Discard"
Confirm that you want to discard the checkout in the dialog box.
You can then make edits to the appointment and ticket and restart the checkout process.
