When scheduling an appointment “By work type group, appointment type, or service territory,” I get as far as “Select Candidate” screen before receiving an error message, “You don’t have any service resources available for the selected engagement channel type.”
I am not sure why it is going to the Select Candidate screen when the appointment was scheduled from the person account, and I have been unable to find any documentation about associating service resources with engagement channels. I have associated the engagement channels with the service resources shift record.
That looks like the standard Salesforce Scheduler component. Because we extended the Scheduler data model to work with Cases and Success Teams, we developed a new component for scheduling appointments in Education Cloud with Salesforce Scheduler.
