Unexpected Update Subnetwork Behavior

EdwardBlair — Tue, 14 Jul 2026 17:50:54 GMT

All -

I'm finding that, once dirty areas are cleaned up, that Update Subnetwork usually returns expected results. But sometimes not.

In the example below I built a subnetwork for feeder 17FL012010 - its the gray line at the bottom. Thing is, all that appeared is what seems to be a line graphic. There is no new entry in the ElectricSubnetLine feature class. I can't select the line or even perform a Pop-up on it.

The breaker (red box) has a subnetworkname assigned, but nothing else does.

Any suggestions on what might be going on would be much appreciated.

Thx,

If you have propagation configured, check that the input field to propagation (phasechange) on the circuit breaker is set to a value other than null, typically ABC

Hi John -

Thanks for the feedback.

Weird. I closed Pro. Logged out for the day. Came back and there was the feeder in the ElectricSubnetworkLine feature class. Maybe I was hallucinating yesterday?

Actually. I just now had the same experience with another feeder.

- Ran Update Subnetwork.

- It completed successfully, but no new ElectricSubnetworkLine feature was present.

- Closed Pro

- Opened Pro a new the subnet line was present for the feeder.

This isn't the expected workflow, is it?

Thx,
