Sewer Directional Manhole Channel, Pipe Connections, and Subnetworks

[Brian_Laws]

I am attempting to set up subnetworks in our Sewer Utility Network in a file geodatabase and I am trying to use the Directional Manhole Channels as the subnetwork controllers for our Sewershed subnetwork.  They are set up just like the regular Manhole Channels, with the Pipe Connections at the end of the Gravity Mains and those Pipe Connections are associated with the Manhole Channel (and all in containment of the Manhole Sewer/Storm Vault).  I change the Manhole Channel to a Directional Manhole Channel and then Modify the Subnetwork Controller to give it a name and define what subnetwork it controls.  But when I go to Modify the Terminal Connections I cannot select the line features for the Upstream and Downstream terminals.  I found that if I connect the mains directly to the Directional Manhole Channel I can select the mains and define the terminals, and I seem to be able to validate and get no errors and run the Update Subnetwork GP tool to propagate the subnetwork name upstream.

I see in the Naperville data that the Directional Manhole Channels aren't directly connected to the main, they have the Pipe Connections just like the regular Manhole Channels, and it seems to be the subnetwork controller for the sewershed.

So my question is there something I'm missing in order to set terminal connections on the Directional Manhole Channel subnetwork controller with mains using Pipe Connections?  Or do the mains have to be directly connected to the Directional Manhole Channels in order for them to be used as subnetwork controllers?

You’ll need to set the terminals on the Directional Manhole Channel, but the key is to define the terminals through the association with the Pipe Connections. When you create or modify the associations between the Pipe Connection and the Directional Manhole Channel, you should be able to assign the appropriate terminal (upstream or downstream) for each connection.

Once these associations and terminal assignments are in place, you should be able to validate and update the subnetwork successfully.

Thanks again Patrick, I knew I had to be missing something.
