These are the two options that an admin has when defining the Visit Duration in a Maps Advanced Visit Plan. Visit Duration is the amount of time that a user plans to spend at each stop on their route. The admin can configure the Visit Duration for a routable object in two ways:

The admin can select a field from the routable object that contains the duration value, such as a custom field or a standard field like Estimated Travel Time. The field must be a number or text field that contains only numbers.

The admin can enter any length of time in minutes in the Visit Duration field on the Maps Advanced Route Waypoint object. The Visit Duration field is a number field that accepts values from 1 to 1440 (24 hours). The admin cannot use fixed values like 60 minutes or 30 minutes as options for defining the Visit Duration, as these are not configurable options in Maps Advanced. The Visit Duration must be either a field from the routable object or a value entered in the Visit Duration field on the Maps Advanced Route Waypoint object.
