Success Factors Integration

Hi All,

For integrating SAP HCM with Success Factors via PI went through number of blogs.

But need some more inputs on the below points

1) Which is the best approach for integration, do we need to use SFSF adapter or SOAP Axis Adapter considering future updates from SAP.

2) In case of SOAP Axis Adapter can we get complete details about the standard  content delivered and configurations of the interfaces.

3) How the Login and Logout messages will get triggered do we need to explicitly execute these interface for each transaction or when we execute any transactions by default Login and Logout also will trigger.

Please provide your inputs and any more additional details with respect to PI based on your experience.

Thanks & Regards,

Prakash
