In the setting: Locations-> Auto ID-> Controls ->Default ID Status we have the choice set to 'Active'.
If you are in scale ticketing and bring up a truck, then click on the 'Assign a Vehicle' button (Ctrl-A), the Location setting is respected with reference to 'Status'. If you go to the Vehicles screen, Auto ID tab, the default value is 'Inactive', even with the Location configuration set as 'Active'. The behavior should be consistent. It will mean one less click for the user.
