We are currently unable to not charge for attendance outside of booked hours. The "no charge" setting on the Attendance screen only applies to booked hours. Discover have advised that this is a "current limitation", so that when attendance falls outside the booked window, the system will always treat that time as chargeable extra time under setting Combined times, even if the booked portion is set to "No charge". I have situations where we do not want to charge the extra hours. We can do a work around to resolve this by adding extra time to the booking and a discount to cover the extra fees, but it means that the printed attendance sheet has inaccurate times. So not an ideal solution either. A proper fix that allows additional attendance to be either "charged", "discounted", or "no charge", as needed.
