I have not tested this yet but I think I may need to enable "Location Aware" for the Configuration Item in the "Behaviors" collection.
I found this description in the LDSDDesigner.pdf
Location Aware – enables you to store location services data for a Service Desk object. This enables you,
for example, to record the longitude and latitude of the device used to log or update an incident, or to log
the location when a user logs on. For more information, see Location awareness on page 43.
CAUTION: Once an object has been made location-aware, you cannot remove this behaviour.
I submitted a ticket some time ago and the issue is reportedly fixed in 2017.3 https://community.ivanti.com/downloads/readme/pages/epm2017.3readme.html#h_defects Defect#383914
After some initial testing with 2017.3 on a Lenovo laptop and Lenovo workstation, I am still not seeing location data in device inventory but still looking into it.
After some testing, Location Reporting is working now and is located in the Device Inventory and Scan File under the attribute "Mobile Broadband - GPS Location"
