This is the most basic configuration option for configuring an Institution or Applicant ID field without using a partition. You should use this configuration when the SIS system provides a single field identifier for a single institution or applicant at a single address.
In this scenario, each record in the institution or applicant extract is supplied by the client, whether it is provided as a CSV file or within a database table, and it should represent a single institution or applicant at a single address. Additionally, one column in the record needs to be a unique identifier. The generation of the institution or applicant pool based upon the institution or applicant extract fails if more than one record shares the same unique identifier.
