A device can travel on a truck rather than in a container. Dockflow links temperature devices to a
container record, so a truck shipment with no container has nothing to attach the device to.
What to do: create a container entry for the shipment and attach the device to it. The
identifier does not have to be a real container number.
Example
A temperature device is traveling by truck without a container, so Dockflow has no container record to attach it to. Create a container entry for the shipment, attach the device to that entry, and use an identifier that does not have to be a real container number.
