Allowing clerks to refund partial stays

Q: When there is a need to back out a charge from the Transaction screen, and I need to select the rate and use a negative number in the "days" field to balance it out, it gives an error that I'm not authorized to enter negative charges. It only does this for the "Reservation" level operator logins, not the "Administrator".  Which access level setting needs to be adjusted to allow anyone to do this?

A: This is the access level "Enter negative amounts for charges or payments" (because the negative rate days results in negative charges).  Go to Maintenance / Park Setup / Access Levels and look for that item.  Double-click on it and set the override level to "Reservations".
