Integrating an external HRIS with SAP SuccessFactors Onboarding requires configuring data transfers and aligning the data model to ensure seamless onboarding processes.

According to the SAP SuccessFactors Onboarding and Integration Guide:

Import Employee Data using Integration Center or OData APIs(Option B): Employee data from the external HRIS must be imported into SuccessFactors usingIntegration CenterorOData APIsto create onboarding records and populate fields like personalInfo or jobInfo.

Configure the Onboarding data model(Option C): The Onboarding data model must be configured to map fields from the external HRIS to SuccessFactors entities (e.g., personalInfo, jobInfo), ensuring data compatibility.

Create an export of new hire data using Integration Center or OData APIs(Option E): New hire data may need to be exported back to the external HRIS for synchronization, usingIntegration CenterorOData APIsto maintain consistency.

Option A (Create an export using only a middleware system) is incorrect because exports can use Integration Center or APIs, not just middleware. Option D (Configure all the Event Reasons) is incorrect because only relevant event reasons (e.g., hire, termination) need configuration, not all.
