There are three areas that need to be mapped:
  1. Ethnicity Mapping
  2. Current Grade Mapping
  3. Relationship Mapping

To map Ethnicity, fields need to exist in Core > Settings > Profile > Ethnicity Types. Once the fields exist, then you can map in onBoard > Settings > SAO Application. If you do not want to use Ethnicity Types, you can create one field called "Not Specified" and map all the Ethnicity fields to that one field.
