Employee data update

Hi,

I am trying to create Emplyee data update scenario for SAP HCM to Success Factor integration in PI 7.4 single stack. I have imported SFIHCM01 and SFIHCM02 in IR.

I have not done anything in IR.

In ID under Business system of SAP HCM I have created one sender communication channel (SOAP sender - transport protocol - HTTP - message protocol- XI 3.0).

I have created one business component BC_SFSF and created two receiver CC one for login and another for rest.

Here I have created 3 ICOs - one using OM for login provided in SFIHCM01

                                          one using OM for upsert provided in SFIHCM01

                                          one using OM for logout provided in SFIHCM01

Now I have 2 questions here -

1. Am I doing it correctly or I need to create separate SWCV for HCM and SF in IR and create the scenario again reusing SIs.

2. Do I need to use Process Integration Scenario (EmployeeDataSynchronization) as well or its not required.

Please help.

Thanks in advance.
