Config Validate Tool R2 utilizes Siebel data to determine if assets are remotely connectable. It leverages the uniquely assigned asset's SEID to reach the particular device over modem or SAL.
If you are not seeing a particular asset after launching CVT and entering the SoldTo/FL, it may point to a problem with the asset registration for remote connectivity. This is typically completed during the technical onboarding phase of asset registration.
With the launch of the Global Registration Tool R3.0, SEIDs can be allocated in a matter of minutes using the Technical On-boarding wizard therein.
