The following error message is received when attempting to perform a directional Fiber Trace:
No fiber objects in that direction.
This can sometimes be caused by unsaved features not yet having been saved to the database.
If you believe you are seeing this message in error please save your edits and try again."
This error occurs if there are no fiber features in the direction of the trace.
The issue may also be related to the following bug resolved in ArcFM 10.1.1:
MM50182 - Fiber Directional Trace intermittently fails to find direction because of difference with Esri precision.
A patch is available for ArcFM 10.1.
