Thanks for any assistance.&nbsp;&nbsp;</P> Wed, 04 Sep 2024 15:06:42 GMT https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1534959#M4269 SusanONeill1 2024-09-04T15:06:42Z https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535205#M4270 <P>Why would you expect from OOTB behavior that splitting a line should be flagged as an error after running Validate Topology? (I just do not know what your use case requires.)</P> Wed, 04 Sep 2024 18:57:52 GMT https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535205#M4270 JoaquinMadrid1 2024-09-04T18:57:52Z https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535216#M4271 <P>The only reason to split a mainline would be to place a manhole or valve there.&nbsp; Rather than rely on the editor to follow through with that, I would like it to identify that just splitting a mainline and leaving it like that is not valid.&nbsp; Under the geometric network, it automatically generated a "Network Junction" to indicate the loss of connectivity.&nbsp; I'm looking for something similar here.&nbsp; Thanks.</P> Wed, 04 Sep 2024 19:15:01 GMT https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535216#M4271 SusanONeill1 2024-09-04T19:15:01Z https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535271#M4272 <P>Based on other posts, it sounds like this is the expected behavior for the Utility Network since the Asset Group and Asset Type of the 2 lines are the same.&nbsp; A "System Junction" is created at the intersection.&nbsp; So I need to figure out another way to enforce the behavior I want - it's not built into the UN.&nbsp; I'm not very familiar with Arcade, but there may be a way to create a Constraint Rule to do the same function.&nbsp; I've tried a few of the "Ready to Use Rules" but without success.&nbsp;&nbsp;</P> Wed, 04 Sep 2024 20:25:28 GMT https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535271#M4272 SusanONeill1 2024-09-04T20:25:28Z https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535482#M4275 <P>&nbsp; &nbsp; I finally found what I needed here:&nbsp;&nbsp;<A href="https://community.esri.com/t5/arcgis-utility-network-questions/finding-system-junctions/td-p/1351529" target="_blank">https://community.esri.com/t5/arcgis-utility-network-questions/finding-system-junctions/td-p/1351529</A></P><P>It allows you to view the system junctions.&nbsp;&nbsp;</P> Thu, 05 Sep 2024 14:16:54 GMT https://community.esri.com/t5/arcgis-utility-network-questions/utility-network-is-allowing-mainline-split-without/m-p/1535482#M4275 SusanONeill1 2024-09-05T14:16:54Z
