Subnetwork problem after upgrade UN v5 to UN v7

Hello,

My team is experiencing an issue with an electric network after upgrading the Utility Network from version 5 to version 7.

When we run Update Subnetwork, every feature in the circuit loses its Subnetwork Name, including the subnetwork controller. We've tried disabling and re-enabling the network topology, recreating the controllers, and several other troubleshooting steps, but nothing seems to restore the Subnetwork Name.

This issue occurs across every circuit in the network.

At this point, the last option we're considering is reapplying the AP, but we wanted to check first to see if anyone has experienced this issue or has any suggestions.

Any ideas?

when you say they lose the subnetwork name, I assume you mean that the subnetwork name becomes unknown? if you run a trace, does the subnetwork include features or not? Can you post a screenshot of the trace results along with the network attributes for the circuit break? Because I think I know the model you're dealing with, I'll use the fields and values from that model (I apologize for the mix of spanish/english).

In particular the Faces operacion and estado del dispotivo of the Interruptor de circuito of the which is the subnetwork controller of the subnetworks. If the faces operacion is set to Desconocido then the entire subbetwork will become unknown (nombre de subred will become deconocido). Similarly, if the controller or the first line's estado ciclio de vida is Fuera de servicio instead of en servicio then the subnetwork will stop at that feature and the remaining features in the subnetwork will become unknown.

Summary:

If the phasescurrent is set to de-energized, that will cause the subnetwork to be de-energized. You should also check to see if the lifecyclestatus of the circuit breaker or the first line in the subnetwork is set to something other than in-service. I normally also suggest checking the terminal connections between the circuit breaker and line, but because these circuits were previously energized that seems unlikely to be the cause of the issue.

That's the weird part... the trace works even though the subnetwork is unknown. The phasespassedthrough are NVR and LifeCycleStatus is "En servicio"

The looks like a bug. It should not be possible for the subnetwork name for a subnetwork controller to be Unknown.

I figured as much. Thanks for your help!
