A field corresponds to a column header in an import file. An example field would be "Age". A field can have multiple values. Values correspond to an enumerated list for the field it belongs to. An example value for the field "Age" could be "21-30".
Raw Fields
Raw Fields are fields that cannot be enumerated because they contain too many unique values. These are not supported via API. Please reach out to your LiveRamp representative if you need to use this field type.
