I imported a feature layer from AGOL and imported it into my ArcGIS Pro project geodatabase as a new feature class called Street_Lights. I then created a new table called Street_Lights_Inspections with a field called ParentGuid of type Guid, a date, and a comments field. I created a one to many relationship class from Street_Lights to Street_Lights_Inspections using the GlobalID in Street_Lights to the ParentGuid in Street_Lights_Inspections. I'd like to be able to add many inspection records to the Street_Lights_Inspections table for each Street Light. When I select a street light point on the map, and click the Attributes tab, I can see that there is a related table as below:
Now I want to add a record to Street_Lights_Inspections. When I right-click on Street_Lights_Inspections the "Add new to relationship" option is greyed out. What could I be doing wrong?
I'm using ArcGIS Pro 2.1.2 Advanced
