SAP SuccessFactors Employee Central uses most of the existing data models in the SAP SuccessFactors HCM Suite. All these data models can be easily identified mainly because they are XML-based and can be found in Provisioning or Admin Center.
Unlike these data models, the Onboarding Data Model is not available in Provisioning and is not used in the other SAP SuccessFactors HCM solutions.
The Onboarding Data Model involves data that will be collected during the Review New Hire Data and Personal Data Collection steps in the onboarding process. Collecting this data is mandatory for an employee’s record in the company.

The Onboarding Data Model is composed of HRIS fields that were already configured for or available in the four data models used by Employee Central.
To configure the Onboarding Data Model, you must select which HRIS fields from Employee Central will be used in the data collection steps of Onboarding.
