SAP CRM and HR/HCM integration

Hi,

We are using ECC 6.0 and CRM 6.0 and we have them integrated using ALE.

The replication works successfully with one exception.

The employment address for the employe is added to the BP addresses with address type "Standard".

We want it to be a Business address type, since the employee home address is the standard one..

I know there are  some user exits on the CRM side  to integrate the replicated data with the BP.

Could you please help me find where the address type is decided while updating the BP?

Much appreciated

Thanks
