I guess you have three options to accomplish this. 1) Use multiple traces, each trace stopping at locations where flow need a value set. This would not be a fast solution! 2) Use a single trace and export the subnetwork connectivity to a json and then read the json, traversing the connectivity and calculating the value. You could do this in python. 3) Write a tool in Enterprise SDK (SOI probably) that performance a trace. Try using the IUNTraceResults4.TraceResultPaths property to walk the connectivity. I have not tried this, but will soon.

check the attributes on the junction features that are used in the subnetwork definition, like lifecyclestatus.

Propagation will not work for this workflow. You could use Functions in a trace. The field you would use would need to be a network attribute. Then you could use a trace to subtract the fields value.

that should work. If you have an existing Utility Network line feature, you would need to create the vertex on these lines, probably using some python code. I would not use split line as that will change all the globalid's which could lead to other downstream problems if you have associations that these features participate in.

The imported junction feature is probably on a location on the line where there is no vertex. When you create the junction using Pro, Pro actually edits the line and adds a vertex.

typically a pole is not part of the Transmission Subnetwork, as a pole or tower can support multiple electrical circuits or subnetworks. However, the pole should have a device or junction feature from the domain network that you could trace from. Upstream and downstream are a little more complicated in a transmission system as a transmission system is mesh, so there is no upstream or downstream. Perhaps the workflow you are wanting is to select a junction and trace from that junction and trace in one direction. You could place a start point at the junction and then put a barrier on one side of the junction to trace in the opposite direction. What information are you looking to obtain from a trace?

Network attributes are assigned to fields in various Utility Network classes. They can be used to control traversability and to allow the field it is assigned to be used in a network summary. They can also make it easier to include fields in network exports. Network Categories are assigned to Asset Group/Asset Types in Utility Network classes and make it easier to include the asset types in network trace configurations. If you had to list the asset types, you may need to use multiple asset types in the network trace configuration, where the categories can be assigned to multiple asset types.

Yes, this is standard functionality in the Utility Network. If you will examine our Electric Foundation Solution, we have many examples of this.

Can you clarify what you mean by duplicated structure layers?

are you talking about a Transmission system or Balanced Three Phase system or an Unbalanced System? Transmission and Balanced are easily modeled using a Hierarchical. If you send me your email address I can add you to a Beta for a Transmission model that is Hierarchical. jalsup@esri.com

If you use the D_Rename option in the Apply Asset Package, as Robert pointed out, you don't have to deal with updating the rules or subnetwork definition. The process takes care of all that for you. If you manually rename, then yes, you will have to deal with changing the rules, subnetwork definition, network categories, etc.

We have a beta version of a transmission model that is hierarchical. If you will send me your email address I will add you to the repository. Jalsup@esri.com

Feild Maps does not support 64 bit objectID's at this time and UN version 7 uses 64 bit objectID's. As for domains, can you clarify this question. May be provide an example.

First download the Electric Utility Network Expanded model from ArcGIS Soutions https://www.esri.com/en-us/arcgis/products/arcgis-solutions/overview After Unzip the file, open the file Electric Utility Network Expanded.aprx in ArcGIS Pro. In the Catalog pane, in the Databases folder, you will see File Geodatabase named ConfigurationForBalanced.gdb. Open this Geodatabase and copy the two files, D_Configuration and D_Rename to the ElectricExpanded_AssetPackage.gdb. Next you can use the GP Tool Asset Package Configuration Report from the Utility Data Management Support toolbox, in the folder, Asset Package, to see result of picking the desired options contained the configuration. Once you are satisfied with your choices, you and use the GP tool, Apply Asset Package or Asset Package to Geodatabase, found in the Utility Network Package Tools toolbox, in the Asset Package folder.

If you don't use junctionobjects, the system will not automatically set the subnetwork name (supporting subnetwork or supported subnetwork fields). Also, information in related tables is not included in an export subnetwork. To use a related class would require a custom tool to assembly the information in to the appropriate place in the json for feeding systems like ADMS or OMS.
