As a university, we use custom fields and participant options on online forms to help us to match incoming data to existing records. We ask for things like Subject of Study, Class Of, Alumnus/Staff/Guest, to help us to figure out whether we can match to an existing record or should create a new one.
We need to be able to see what people have entered into these fields when we are linking records in Online Data Review.
I agree. The participant options field in general is not very available to view/query/etc. Please expand field access.
I absolutely agree. Trying to match someone from thousands of alumni records when the event registration is very scant is almost impossible. The fields Cerys mentions above are essential for us to be able to match to existing alumni.
