I created a City entity where "name" is the city name and state is the associated state. I imported all cities/state combos in the USA. Now I'm have a face to palm moment. When I try to import contacts or cases that use the City lookup, it fails with a "duplicate lookup reference was found."
Is there any way to have the import look at two fields to determine uniqueness?
If not, I'll have to delete all the city records, create an oncreate workflow to create a compound key, then add that to my import file; something like citystate concatenation.
