In E1 9.2 Transportation, what number do we use for a carrier when we have a private fleet?

Hello MOSC,

In E1 9.2, we are preparing to add the transportation module for outbound shipments to the existing instance of E1 which already has inventory, sales, procurement, EDI, and advanced pricing.

We will use both common carriers for truck freight and our own fleet of tractor trailers.

When we create a sales order and shipment, what do we enter for the carrier number when we use our private fleet?

Do we use the address book number of our company and add it to the Carrier Master?

Do we create a new  address book number and add it to the Carrier Master?
