You want to perform the update of the booking day but not all guests arrived for today. If you can assume that the guest will not arrive anymore, please leave the guest untouched on the arrival list and perform the update of the booking day as usual .
You get a security query due to the non checked-in guest, which in this case is to confirm with “OK” to fulfill the update of the booking day.
Via the task management, you can also check your reservation details and edit the invoice.
