Tables and Relationships

Question

I have a feature service that contains a feature layer ("Management Regions") and several tables. The layer has a M:M relationship with Table 1 ("Source"), and that table has M:M relationships with the other tables. When I add the layer as a FeatureLayer, I can see the Source relate using the relationships property. However, if I add the table as a FeatureLayer, its relationships property is null. Is there a way to get the relationships for the table? const regionLayer = new FeatureLayer({ url: 'https://services2.arcgis.com/blah/FeatureServer/0', outFields: ['*'] }); const sourceTable = new FeatureLayer({ url: 'https://services2.arcgis.com/blah/FeatureServer/1', outFields: ['*'] });‍‍‍‍‍‍‍‍

Hi there, Are you loading your non-spatial table? Non-spatial table instance can be created from the table url in a service and the table must be loaded by calling load() method. // Add a non-spatial table.require(["esri/layers/FeatureLayer"], function(FeatureLayer){ // points to the non-spatial table in a service storing San Francisco crime incidents. const table = new FeatureLayer({ url: "https://sampleserver6.arcgisonline.com/arcgis/rest/services/SF311/FeatureServer/1" }); table.load().then(function() { // table is loaded. ready to be queried on the server. }); }); Here is a doc: FeatureLayer | ArcGIS API for JavaScript 4.17
