In Mapp Engage, you can create enumerated attributes automatically with a CSV or XML import of contact data.
CSV: New attributes are automatically created during the import of a CSV file. If the attribute contains less than 1,000 different values, it is automatically enumerated. If an attribute contains more than 1,000 different values, the import fails. All the values that are stored in the attribute automatically become possible values in the enumeration. For more information, see CSV Format for Contact Imports.
XML: The command to enumerate the attribute must be explicitly entered as enum="true". For more information, see XML Format for Contact Imports.
