If you want to see the records name of a parcel, line or point in the popup, you can do that by using an Arcade expression.
Here are the steps:
1. Right click on the layer --> Configure Popups
2. Press the Expressions on the bottom

3. press New to add a new expression and give it a name and a title:
![](/legacyfs/online/504705_pastedImage_2.png)
4. Add this expression
var RecordName = First(FeatureSetByRelationshipName($feature, 'RecordHasTax', ['Name'], false));
return RecordName.Name;
5. Modify the name of the relationship class (bolded above)

6. Test by clicking on a feature (you can apply this to a parcel, boundary line, connection line and points)
