How to associate ArcGIS Tracker data to a unique ID?

[NickShannon2]

Recently aquired ArcGIS Tracker and learning the ropes. 

I've enabled Tracker & captured some data. 

My question is:  If I have an assignment number — how do I assoicate that with the ArcGIS Tracker data?  So I can delinigate tracks based on assignment number.

You'll need to compare timestamps. If you know when the assignment was started and when it was completed, you can query those tracks with a datetime where clause using the "location_timestamp" field.
