In SAP SuccessFactors Employee Central, model base objects are utilized in business rules for scenarios such as:

A. Trigger Workflows

Model base objects can be used to define conditions that initiate workflows, automating processes based on specific data changes or events.

C. Trigger Rules for Hire/Rehire

During the hire or rehire process, model base objects help in setting default values, validating data, and enforcing business logic to ensure compliance with organizational policies.

Options B and D are not typically associated with model base objects in business rules:

B. Trigger Rules to Display Internal Job History

Displaying internal job history is generally managed through reporting and does not involve model base objects in business rules.

D. Save Changes to Foundation Objects

While foundation objects are essential for organizational data, saving changes to them does not typically require the use of model base objects in business rules.
