Third Party Reservations are reservations that come through a 2way (aka Channel Management, BW, Siteminder, SynXis, Innlink).

Every reservation that comes through a 2Way should always have a Rate Code/Discount Code assigned and each Rate Code has a default Marketing Segment set up in the translation table* in the 2Way interface.

When a booking comes in with that Rate Code, those Segments will reflect in the reservation. This setup can be modified* in the rate mapping as well as within the reservation itself.
