Gate Check In
The Gate Check In page is used to check-in equipment as it pulls into
         a yard or when the driver notifies yard personnel of arrival and shows the paperwork for
         equipment. The Gate Check In page captures details required based on
         equipment flow and check-in. 
   Note: Multiple ASNs are automatically
            linked during Gate Check In; you receive a message containing the number of ASNs linked
            to the equipment. When only a single ASN or no ASN is indicated during the Gate Check In
            process, no message is shown.
