I want to batch update the university affiliation (student, faculty/staff, alum, etc.), which we will save to the ‘Target’ field under Demographic. I've found how to import and batch update constituent addresses, and how to batch add constituents, but there doesn't seem to be a way to import and batch update other information tied to individual constituent records. When I run it with the Lookup/Constituent ID and Last Name to match records, it finds that everyone is a ‘duplicate’ constituent and throws errors. Has anyone else dealt with a problem like this, and how did you solve it? Thanks!
