SAP HR Employee Master Data to SAP PI

Dear all,

My requirements are,

Whenever a employee get created/Deleted/Update in SAP HR system, I would like to receice the information about the employee in SAP PI from where I send the info to Non- SAP application. I need information from only some info types not all of them.

What I did

I had used Change pointer and IDOC type HRMD_A07 to receice the data. Activated filter in SALE for this IDOC type. Everthing works fine.

But now i am thinking to use ABAP proxy instead of Standard IDOC and Change pointer concept. I need to find out a user exit or BADI at where I can call my proxy class to send 25-30 fileds to SAP PI via ABAP proxy.

Have anyone done this before? If yes. let me know the details.
