I would recommend you create an idea for this, but do it in the data management community since this is much broader than the utility network. In terms of a way to capture what you're looking for, you could use version differences to find all the newly created features in a version or you could use an attribute rule to respond to the edit. ...

You should be able to find an example you can adapt in the attribute rule github repo: arcade-expressions/attribute-rules/attribute_rule_calculation at master · Esri/arcade-expressions · GitHub. Something like the "Contain feature in a container within a search distance" would be a good place to start. ... View more

Because a group template or preset template can contain multiple features, it doesn't make sense that we would be able to provide a single row token back for the operation. ... View more

Directional terminal configurations control the flow within a device, but do not affect the directionality of flow of the lines connected to them. Subnetwork controllers, and whether they're a sink or source, determines what is upstream and downstream in your network. Look at your connectivity rules to determine how to appropriately connect lines to devices with that terminal configuration. In the case of port two in the pipeline model the bidirectional dual terminal configuration is used for the emergency valve that act as subnetwork controllers for your isolation tier. There is no directionality on those devices or their terminals because gas can flow freely through the valve in either direction. ... View more

No. You don't have to delete the feature, but you need to use the modify subnetwork controller tool to remove the old subnetwork from the feature and add the new one. You should then follow the steps in the online help to completely remove the old subnetwork from the system so it doesn't appear in any of the dropdowns or tools. ... View more

If I was trying to estimate the feasibility of connecting a new service, my preferred approach would be integrating my UN with a hydraulic model. For basic feasibility like this I would calculate the number of customers per pressure zone, which you can do by adding a summary function to the subnetwork definition for your pressure zones. You can see an example of this in action in this tutorial:https://learn.arcgis.com/en/projects/get-started-with-arcgis-utility-network-for-water/ You can only support so many customers in a pressure zone before you degrade the water pressure, so you'd want to rely on the number of customers in the pressure zone. Looking at the upstream/downstream doesn't work in a looped pressurized system. You could try and do something with an isolation trace, but it'd be a lot of work to build something scalable to do that, and it would be more reliable to look at the pressure zone anyways. ...

You can use a function to calculate a value using the attributes of the features upstream of the manhole. If you need something more advanced than that you would need to write something to perform the calculation, using the features returned by the trace. ... View more

It makes your life easier to communicate with other utilities or contractors if everyone uses the same terminology, but every utility has unique naming standards. If you do need to rename things use the D_Rename table to manage the rename, so it handles updating all the rules and configuration. Read this blog if you are unfamiliar with this process. You'll still need to adjust any existing maps or applications you've configured that reference specific asset groups or asset types by name. Once you've deployed a utility network you cannot rename asset groups or asset types, so if you've already deployed and want to make this change, you'll need to go back to an asset package and deploy a new database and services. For a list of what you can/cannot change, and when, refer to the Utility Network Management Tasks page of the online help. ... View more

Can you explain what you mean by changing the order of tiers? Each tier has its own unique tier rank that controls tracing. This is how the system knows that high voltage is upstream of medium voltage and low voltage is downstream of medium voltage. Once you've added a tier group or tier to a utility network you cannot remove it. However, if you export your data to an asset package you can them remove the tier/tier group from the model (along with all its configuration) either manually or using the D_Configuration table. ...
