This is covered in this page in the online help: Utility network management tasks—ArcGIS Pro | Documentation Renaming asset types is not currently supported (as discussed in this community thread). Adding new asset types can be done, once the topology is disabled, but you must make sure that you apply any other necessary configurations while the topology is disabled like adding rules, network categories, and updating any relevant subnetwork definitions to include the new asset type as a valid line/device/etc. ...

While this feature is planned to be added in a future release, you currently need to export the utility network to an asset package, make the change, and stand up a new geodatabase. You will not be able to retain history or versions through this process, so you should think carefully before doing this and ensure there aren't any other significant changes you need to make at the same time. ...

What @CodyPatterson is describing sounds like about 2x the specs of the reference architecture for a mid-sized gas utility (300k connections). You can find one of the test studies for that architecture (including performance graphs) here: Test Study for a Network Information Management System Gas Utility (SQL Server) | ArcGIS Architecture Center ...

To properly determine these answers, you'd need to go through a capacity planning exercise that takes into account your specific workflows and expected loads. Outside if that, you can find guidance on the ArcGIS Architecture Library on how to begin to size a system. You can also find reference architectures and test studies that show system utilization for specific logical/physical configurations (with specs of the hardware used). ... View more

You can find the code here: arcgis-pro-sdk-community-samples/UtilityNetwork/Calculate Flow Arrows at master · Esri/arcgis-pro-sdk-community-samples. The original article has also been updated to include this link. I'm curious why you're running this against a water network, given that its mostly looped. Are you looking for areas that aren't looped? Are you just using it to verify that everything is connected? Are you hoping to build some kind of hydrant flushing application? The community sample does take into account all the subnetwork controllers for the subnetwork. Because it is a community sample it was written to be easily understood, so there are many optimizations that could have been put in place to make it faster but were omitted for clarity's sake. ...

Don't worry about it, we keep a swear jar of sorts around the office for every time someone forgets to check the subtype 🙂 ... View more

@EdwardBlair what version of the model are you looking at? In the latest versions of the model both the devicestatus and normalposition fields have domains that only include the open/closed values. In earlier models, there was a domain assigned at the class level that also included active/inactive, but the domain assigned to operable devices should only include the values open/closed. As you know, when a class has subtypes, you must look at the domain assigned at the subtype level. ... View more

I believe that this is the purpose of an Emergency Controllable Valve. They are controllers in the isolation zone tier, but I've also seen them used to indicate the boundaries between pressure zones. As always, I defer to @TomDeWitte about all UPDM modelling questions.   ... View more

Device status controls tracing, normal position does not. ... View more

You would need to write python to turn the features into trace locations for that tool. You'll need to know the network source id, global id, terminal id (points), and percent along (lines) of the starting location(s). ... View more

it's odd that there are two three phase units in that device. Double check the status, phase, and connectivity associations of both units to ensure that they are stopping the trace. A quick way to test this is to create a version and delete both units. If you do that, then there should be no way for the trace to go from one terminal of the switch to the other (terminal path = None, no units, no j-j connectivity). ... View more

@BillShoop do the lines on either side of the switch belong to the same subnetwork? Are they connected to the same terminal on the switch? ... View more

I don't know the dates or timelines for patches, but if you log a case with support, they should be able to get you a window. The issue also affects ArcGIS Enterprise 11.5. Once the 3.5.5 patch comes out you can test out the fix in a local geodatabase, but to see the fix in ArcGIS Enterprise 11.5 you'll need to wait for a patch on that release. ... View more

This is likely related to BUG-000179357. Please log a case with support to get attached to the bug. In order to see the correct behavior you will need to wait for the next ArcGIS Enterprise patch for a network management release (11.1, 11.3, and 11.5). Refer to the bug for more details. ...
