SAP delivered SAP-SuccessFactors Integration Package 1 in May 2012. This package extracted employee and organizational data from SAP HCM OnPremise and created a file that can be uploaded to SuccessFactors Business Execution Suite.
The functionality for delta data extraction is now available. Customers will be able to run a program to extract employee and organizational data that has changed since the previous extraction and create a file that contains only the content that has changed. This 'delta file' can then be uploaded to the SuccessFactors business execution suite.
If you are a current SAP - SuccessFactors Hybrid customer, you can access the integration package and the updated administrator guide from service market place.
