For each computer (or device) that uses Dentrix Ascend, you can choose to have a warning message appear or not when you attempt to double-book a provider.
To turn on the warning for double-booking
On the Schedule menu, click (or tap) Calendar.
The Calendar page opens.
On the View menu, set the Warn when double-booking switch to On.
Click (or tap) Done.
With the Warn when double-booking switch set to On, if a provider is assigned to a scheduled appointment, and you attempt to schedule another appointment with that provider that conflicts with any part of the time of the appointment that is already scheduled, the Select Time Slot dialog box appears.
Then, you can do one of the following:
Click (or tap) Cancel to change the provider, time, or day of the appointment being scheduled currently so there isn't a conflict.
Click (or tap) Save to schedule the appointment anyway.
Note: To return to not showing the warning on the computer (or device) that you are currently using, on the View menu of the Calendar page, set the Warn when double-booking switch to Off, and then click (or tap) Done.
