Close Hotel
The Hotel date is a specific date of each Hotel - don't confuse it with the current date (they could be different).
At Hospitality->Hotels->Utilities there is a special procedure name Close Hotel
This procedure is usually run after 12 mid-night every day and it adds Debit Amounts for every occupied room.
Here is the window of the procedure:
Before running the <Close Hotel> you run first the <Test Hotel> procedure to catch any errors in the system - usually Reservations that must have been check-In.
If there are NO errors you can run the <Close Hotel> and the Hotel date increments one day.
* Note: this procedure cannot be reversed.
