Hi, trying to do an import into a custom entity which has a lookup to account, contact, and user entities. I keep getting the error "A duplicate reference was found" on the mapping to the contact entity. I turned off all duplicate detection as well. I'm basically trying to map records into a custom entity that may have references to the same company and contact multiple times. How can I have this associate the record in the spreadsheet to the same contact each time? Do I have to use the GUID of the contact or is there an easier way to do this?
