Definition
A carrier subset of a Mode (when it is defined). This subset can represent a different type of delivery vehicle or a different actual carrier.
A preferred carrier is a setting on a demand line that designates the carrier that should be utilized--if a solver is run, that preferred mode and preferred carrier will be used to service that demand.
Availability: Enterprise Subscription Only--Enterprise subscribers can also define what a Carrier means in their reference dataset.
Example:
In the standard enterprise data set, Parcel has two "carriers":
Standard (also known as ground)
Expedited (also known as 2 Day)
