Overview
In case there were multiple vehicles allocated to a transport, but only some of them were used to successfully complete tracking, this warning is shown:
With this warning, Visibility Hub provides insights into the tracking logic and possible allocation issues/problems that should be reviewed by the party who allocated the vehicles to the transport.
Details
There can be different reasons why some of the allocated vehicles are not used to track the transport:
The first vehicle in line didn't visit the loading stop before one of the subsequent vehicles allocated to this transport did
A planned tractor switch wasn't executed because a new real-time vehicle allocation was received earlier than the planned switch.
Vehicles planned to visit the final stop(s) of a tour are not used because a "earlier in line" vehicle was visiting the remaining stop(s) and therefore completing the tracking of the tour already.
Etc. (this list is not exclusive)
Note that this warning is only shown when the transport state is "Completed".
Potential tracking problems
It can happen that vehicles allocated to a transport, that are actually not meant to execute this transport, contribute to the tracking in some way, for example: Unintentionally trigger the tracking to start or, in case of multiple vehicles being involved, the tracking stream switches to a vehicle that is not meant to be tracked.
This can lead to wrong tracking data shown to the customer as well as incorrect ETA information.
