Automation Buttons clears selected orders in a ticket by default. You can prevent that behavior by disabling Clear Selection setting.
I can’t give a specific example for that setting but you’ll know when you need it…
Edit: A use case might be order tag selection screen. When you do not select required order tags SambaPOS will display a warning to make required selections. However modifier screen will disappear as you’ve clicked Close Ticket button. If you disable Clear Selection for Close Ticket button modifier screen does not disappear.
