Hi Robert, Is flow direction when using subnetworks not stored anywhere in the network, but is instead calculated dynamically every time it’s needed? Could you get different flow directions from using a different tier with different subnetwork definitions? Thanks for your help!

What is the purpose of the service territory? Is it to prevent you from creating features outside your service area or is it a performance enhancement where restricting the extent of your network improves performance? If it is performance, is it a proprietary discussion or could you explain how the service territory impacts the back end of the UN?

Thanks Robert! This really starts to lay down your options and decisions. I was not expecting that connected traces used subnetwork controllers. I need to see how using sinks compares to digitized direction. I imagine that the worst case scenario would be that some pipes would be marked as indeterminate even though the pipe slopes in a certain direction. Is the algorithm in the geometric network for setting flow direction similar to the UN? Yes, I understand the concept of an isolation trace in water, but I was wondering how it actually worked and how it might be applicable to sewer systems. One use case for us would be how do you divert flow around an SSO. We can figure those things out manually with good data and symbology. However, a flow trace that told you where to place a stop log to isolate an area would be more expedient in an emergency just like water crews trying to figure out which valves to close. If we were using digitized direction, it would come down to what isolation devices, in this case stop logs, would block (redirect) flow from reaching the problem area. We have more needs than this. We need ways to design, track, and share flow diversions across the organization and integrate them into the work management system. We've been gathering requirements internally and I've been trying to think of an information model for representing flow diversions. Some of the flow diversions may be partial. Some of them may be complete. They all involve some upstream device(s) redirecting flow and they impact some set of downstream features. Diversions are used to reduce flow to treatment plants for maintenance, pipes for construction, or manholes that are overflowing. There are scheduling component, data editing, design, and sharing components. I would be interested in talking about this more in the future. I imagine that the power of the UN trace tool could lead to custom geoprocessing tools that can perform more advanced logic through multiple traces combined, that is if it you can't do it with one trace. It would be nice if there is a chart or a blog showing which traces have multiple passes, what each pass does, and which traces use subnetwork controllers. I will try to do my own research. The concept is a little bit hidden at first when you are learning the UN. It's really important with the filter barriers. It would be nice if that was more explicitly discussed.

Thanks @gis_KIWI4 and @RobertKrisher. My follow up questions are: 1. Can subnetworks be defined using digitized direction? 2. What won't work if you do not set up tiers and subnetworks and use digitized direction only? Is it just the subnetwork trace? Is it also the isolation trace? Is there any other functionality in the UN that depends on it?

I'm trying to apply the concepts of subnetworks and tiers to our sewer system. It appears that subnetworks were designed for systems where the resource flows out of a source or into a sink. It looks like the subnetwork controller determines the flow direction in the subnetwork. A subnetwork in a sewer system would be analogous to a tributary area. However, our system has manholes where flow bifurcates into multiple paths. Instead of paths always consolidating, sometimes they split. A point can drain to multiple sinks. This would lead to multiple subnetwork controllers. Can a node or edge in the UN participate in multiple subnetworks? The option of using digitized direction like we did in the geometric network may be required for us. Next, are subnetworks and tracing by digitized direction mutually exclusive? If both are possible, would the subnetworks be defined using digitized direction in your subnetwork definitions? Finally, are subnetworks and tiers required at all? I can see why they would be necessary if you have no other way to define flow direction. If you do use digitized direction, can you just never setup tiers and subnetworks? I notice they don't exist when you build a UN from scratch. What functionality do they enable?

Is the following accurate then? 1. UNs in enterprise geodatabases require branch versioning to edit. Branch versioning is only available through ArcGIS Enterprise and enables multiuser editing. The libraries that make the updates to the RDBMS are in ArcGIS Enterprise. ArcGIS Pro, web, and mobile clients use the same patterns to edit through web services. 2. UNs in file or mobile geodatabases are inherently single-user. Editing these geodatabases requires libraries that are only available in ArcGIS Pro or the Runtime. The client modifies the file-based geodatabases.

What forces you into publishing your UN as a feature service to edit it? Can you edit a UN in ArcSDE if it is not versioned? Is branch versioning the only thing that forces you into publishing your UN as a feature service? I understand the general concepts of the UN being service-oriented, but I'm trying to understand how the software forces you from editing a UN in a FGDB into editing a UN in a feature service with branch versioning.

Is it possible to create a trace configuration that finds the intersection of multiple upstream traces from multiple starting points? Alternatively, do you have to perform multiple traces and intersect the results? The use case I am trying to support is finding a blockage or change to a sewer system that could have created observed impacts at two different downstream locations. It helps to speed up troubleshooting.

Thank you. That is very good information. Right now, we are at ArcGIS Pro 2.9.14 and ArcGIS Enterprise 10.9.1, but we're getting a lot of pressure from some users to upgrade. I need facts like this that demonstrate incompatibilities.

I'm trying to find out if and to what degree ArcGIS Pro 3.5 is compatible with ArcGIS Enterprise 10.9.1. I want to know what will work and what won't work. Thanks for any help.

From what I remember, it was successful. It might have also been that I wasn't logged in to see all of the services because they weren't all shared publicly.

I narrowed it down a little bit more. Yes, the angle in the renderer was zero, but it is also that way on the service. What was missing is the visual variable for the rotation angle. The visual variables were an empty array somehow. I think the issue is in the _createOperationalLayers method of the printTask. I created a workaround by adding another function in Print.js of the Print widget to put back the visual variables that were missing. This function is like _fixInvalidSymbol and _excludeInvalidLegend.

I'm migrating a Web AppBuilder application from a custom print service hosted in ArcGIS Enterprise 10.6.1 to ArcGIS Enterprise 10.9.1. The 10.6.1 service was published from ArcMap. The process was simply to run the Export Web Map tool with a folder of custom templates and share as a service. The 10.9.1 service was published from ArcGIS Pro. When you observe the web traffic, the web map for 10.6.1 includes feature collections with a symbol for each feature that includes the point rotation. When you look at the web map for 10.9.1, the layers are much simpler. They are mostly just a URL and a renderer. The renderer has a rotation angle of 0, which is how all points are drawn in the PDF export. I'm wondering if anyone else has had similar issues before. This may just be a Web AppBuilder issue. It is the client submitting the request. I am able to get the print job to work properly if I pass the web map JSON created for the 10.6.1 service. Any help is appreciated. Thanks, Nathan

Hi Michael, We have some large raster catalogs that we will be moving to mosaic datasets in the near future and a custom flow trace that uses the geometric network. So, things that ArcGIS Pro doesn't support.
