Q: Sometimes a clerk enters a payment or deposit through Customer Details instead of through the Reservation. I know we aren't supposed to do that, but is there any way to keep them from doing it by mistake?
A: You can set the Access Level so that only Administrators or Managers are allowed to enter Customer transactions.
Go to Maintenance / Park Setup / Access Levels. Look for the entry "Enter Customer (non-reservation) transactions", and double-click on it. Then change the New Minimum Access Level as desired.
