I have a feature service and a related table linked by a text field (hosted on AGO). I understand that global ID - guid link is ideal for creating relationship classes, but this was unavoidable for the project. I am opening the S123 from URL with the primary key field pre-populated with string value. It is set as read-only in S123
Am I trying to do something unsupported by S123 here? Should relationships be created using only GlobalID-GUID fields?
