I have filled out the ACA sample files provided for the California 1095C State Mandate with our data. When I go to import the files I open the employee file first, do all the mapping and then on Step 4 I try to Test parse data. It runs for a minute and then I get this error, "index or primary key cannot be null" The sample files do not provide a column for an index or primary key and I am not sure how to get past this error.
Has anyone run into this issue? How did you solve it?
Thank you,
