I suggest that you contact Esri tech support so that we may get the data in house and determine what could be going on with the state of the network. Regards, Jay Sandhu

The main reason why an existing network dataset shows Not Built status is if dirty areas are present. You can check that by add the Network Dataset to ArcMap. Then in the TOC, right-click the network dataset and bring up the properties of the network dataset. On the symbology tab, check on the Dirty Areas and click Ok. You may choose to turn off the drawing everything else off. Are there any dirty areas present? If there are no dirty areas present then it could be some issue with way the system file date/time stamp is being recorded and read to say that their are newer files then when the network dataset was written.

Is the Not Built status showing up on the same machine on which you built the network? The check for built status is based on the date time stamp on the files on disk. Sometimes the clocks on various machines are not synchronized. And are you sure no other process is editing the network dataset after you have built it? Also what do does line mean in your question: " And the NA Server which is using the network data source is correct" Jay Sandhu

This looks like an existing network dataset is being re-built. Is it possible that you have another process using the data at the same time, like running a solve on it? Jay Sandhu

What software are you using? ArcMap, ArcGIS Pro, online services? What network dataset are you using? When you solve the route and the service area, do you use the same costs/restrictions, i.e. the same travel mode? If everything is the same, can you do the service area with the "detailed" option and then compare results? Jay Sandhu

It does sound strange, especially when in Pro, OD and Service area are working correctly but not Route. Are you using the same network dataset for these tests? Can you add two stops to a new route layer by using Edit/Create and click them further away from the network edges and do they route? If that does not work, perhaps the issue is with the network or spatial reference. Jay Sandhu

The SDC is a highly compressed read-only format. So it is not possible to edit/re-build that network. If all you want to are intersection points, then one way could be create points at the start and end of each line. Use the GP tool Feature Vertices to Points with the option to write out both ends (for the streets.sdc file). More help here: https://desktop.arcgis.com/en/arcmap/latest/tools/data-management-toolbox/feature-vertices-to-points.htm This should account for most of the intersection points. Some will be duplicated and you could remove the duplicates with the GP Delete Identical tool. Here are some links to previous discussion on intersections and SDC data that might come in handy. https://www.esri.com/arcgis-blog/products/arcgis-desktop/analytics/more-adventures-in-overlay-creating-a-street-intersection-list/ https://community.esri.com/thread/21850 Regards, Jay Sandhu

When the build network process is running, it writes to a log file called "build.txt". This file can be found in a sub folder for current arc process in the system %TEMP% folder. Examine the contents of that to see where it is spending the time. This might help find the culprit of the slow build times. Also, even if a spatial index exists on your feature class, you may want to re-build it in case it has become stale for some reason. Jay Sandhu

Network Analyst route solvers minimize cost attributes. So if changes to the network add new edges or change the travel time on the edges then you can run the OD to measure the before and after shortest path costs and compare. Network Analyst does not have notion of capacity on an edge, only cost to travel on it. For capacity, you will have to figure out the updated travel times on those edges and recompute the OD.

You can also look at using the GP tool Dissolve Network to remove two valent junctions and chain up multiple edges into one edge. Helps reduce the number of edges in a network and improve performance. More info here: https://pro.arcgis.com/en/pro-app/tool-reference/network-analyst/dissolve-network.htm Jay Sandhu

You mentioned that you used Add Locations with the "use network location fields" parameter selected. This means you are telling Add Locations to skip the geometric searching. The network location fields are most likely stale and that is why the start/end points are not being located. You should use the "Use Geometry" instead with the Add Location and the stops should be located. Network Location fields can become stale if you edited/re-built your network or are using a different network then the one on which the fields are computed. Network Location fields make it faster to add stops to network analysis layers but you have to recompute them if/when the network changes. Jay Sandhu

There are really no good sources of free street networks available. If you have a region in mind, you could try to find if the local city agency has some data. Or you can go to places like TIGER (US Census Bureau) or openstreetmap.org to download data. You will then have to create the network dataset. You can search for tools to convert the openstreetmap data into a network dataset that can be used with ArcGIS. Some info here; https://www.esri.com/en-us/arcgis/products/arcgis-editor-for-openstreetmap I will suggest that you create a free trial account with ArcGIS online and try out the Vehicle Routing Problem solver and see if it works for your needs. It might be cheaper to use the high quality data online by using credits then finding/maintaining free street data. Jay Sandhu

The directions capabilities are set in the network dataset. Does you street data feature class have a street name field? If yes, then you can update the network dataset properties using ArcMap. The ability to configure the network dataset for directions is not available in ArcGIS Pro yet, but coming shortly. You can read more about this here: https://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/setting-directions.htm Jay Sandhu

Travel modes is also a fairly new concept in network datasets. So if your network dataset does not have them defined, then the Make Service Area Analysis Layer tool will use the cost attribute that is set as Use by Default. Typing in the name of one of the cost attributes does not mean it will be interpreted as a travel mode. Travel mode is a collection of cost, restriction and parameter settings. You can read more about them here: https://desktop.arcgis.com/en/arcmap/latest/extensions/network-analyst/travel-modes-concepts.htm I will suggest that you bring up the properties of the network dataset in SDE and then define at least one travel mode based on the attributes of the problem type you are solving. The new Make Service Area Analysis Layer makes it easy to solve using a local network datasets as well as with logistic services from a portal connection like ArcGIS online. Otherwise the old deprecated tools still work, but are not recommended moving forward. Jay Sandhu

Most likely you choose the "Split" option in Pro. That is, split the area evenly between service areas. If you use the default "Overlap" option, you should get results similar to ArcMap. Or in ArcMap, you can choose the "Not overlapping" option and get similar results as your Pro screen shot. Jay Sandhu
