About this question
We recently started using Salesforce's Survey tool and are having trouble reporting on it.
When I look at a SurveyInvitation in Lightning, one of the fields I can see is "Participant", and I can also see that field in the Object Manager for SurveyInvitation. Here is what I see in Lightning Experience:
I've created a straightforward custom report type to report on SurveyInvitations. However, in the "Fields Available for Reports" section, there is no Participant field.
Why is this? Is there any way to make the field available for reporting? How to get an object report? I have already checked in Object Manager that it is not a field-level security issue.
