The oData query I got using the oData Query designer is the following (the guid is a sample)
ServiceAppointmentSet?$select=Resources&$filter=ActivityId eq guid'83CA6B11-6C0A-E311-8BB5-B499BAFE71A5'
but in the response i get an error that the Resources field was not found.
I tried without the select, and debugged the returned oData object, but noticed that it doesn't show both Resources and Customers partylist fields that are in ServiceActivity.
ServiceAppointmentSet?$filter=ActivityId eq guid'83CA6B11-6C0A-E311-8BB5-B499BAFE71A5'
Does anyone have any ideas?
