What's the difference between inventory and transit sites?

Assuming you are operating in a multi-site environment, the majority of your sites will be inventory sites. An inventory site is a site where inventory is physically produced or stored. Transit sites, on the other hand, are a type of temporary site used by transfer orders to hold inventory when it is in-transit between two sites. A transit site could be a truck, a shipping container, or a ship. If you are not using transfer orders, then you will not have access to transit sites.
