I'm using Locate Feature Along Routes to locate my points on a route all defined as shape layers on same coordinate systems. But it doesn't work. The points won't be located and the generated table is blank.
When crazy things occur using points along a route, here in this thread I mentioned some things I try....
The most common issues I see when I use the tool:
1. No ESRI recognized ObjectId in the event/overlay layer
2. Projections not the same
3. No valid route layer
4. Screen refresh lag ... some times at a range of specific zoom levels the data will not display or disappears.
Hope some of this helps...
