https://community.esri.com/t5/electric-questions/modify-associations-not-recognizing-assembly/m-p/1068864#M722 <P>Hello, I have recently come across a strange issue when adding new assembly features to an existing project. I want to make the assembly point a container and place other devices in containment. This is something I have done hundreds of times in the past. I have over 200 assembly point entries, all that are containers.&nbsp; The problem occurs after the assembly feature has been added and I go to "Modify Associations," I get a yellow warning in the "Modify Associations" pane that "No valid features have been selected." To add to that, when I go back and select other assembly features that I have already created and have features already in containment, I get the same warning. I have checked the rules, I have set the association role and nothing seems to fix this issue. I thought maybe it is because I added a join to the feature class but, I have joins on other feature classes and I am able to modify their associations. Has anyone experienced this issue?&nbsp;</P> Wed, 16 Jun 2021 13:22:36 GMT DavidNuhn 2021-06-16T13:22:36Z https://community.esri.com/t5/electric-questions/modify-associations-not-recognizing-assembly/m-p/1068864#M722 <P>Hello, I have recently come across a strange issue when adding new assembly features to an existing project.

Have you tried Pro 2.6 with ArcGIS Enterprise 10.8.1? There has been some improvements in the Modify Associations pane:</P><P><A href="https://www.esri.com/arcgis-blog/products/utility-network/announcements/whats-new-for-arcgis-utility-network-in-arcgis-pro-2-6/" target="_blank">https://www.esri.com/arcgis-blog/products/utility-network/announcements/whats-new-for-arcgis-utility-network-in-arcgis-pro-2-6/</A></P><P>I'm wondering if you would experience the error that you are getting when using a newest version of UNM.</P><P>Regards</P> Mon, 06 Sep 2021 00:59:50 GMT https://community.esri.com/t5/electric-questions/modify-associations-not-recognizing-assembly/m-p/1095635#M735 DanielSimo 2021-09-06T00:59:50Z
