User data comes from multiple sources, including the following:
Human Resources Information Systems (HRIS) (either manually or automatically)
Spreadsheets
Databases
CSV
Regardless of where the data comes from, it must first be organized and formatted to be recognized and accepted by SAP SuccessFactors.
The User Data File (UDF)
The basic import file or User Data File (UDF) is a CSV file and consists of standard data elements. These are required fields, filter fields, and optional fields. Fields vary based on your configuration and tools, but some of the field requirements for the User Data File that must be provided when importing new employees or modifying existing ones are: STATUS, USERID, USERNAME, MANAGER, GENDER, FIRSTNAME, LASTNAME, DEPARTMENT or TIMEZONE

To begin an implementation, download a blank template that you download directly from the tool to create new users.
Watch this video to learn about the User Data File (UDF).
Rows 1 and 2 of the template (System ID and Label, respectively) must be preserved.
Your training instance already includes a set of users, including managers and direct reports, that will be used in later exercises.
