Replication of BPs in CRM to ERP(3rd party WS calling)

Hi experts,

I am quite new to CRM.I have a requirement where Master data (business partners) will flow from CRM to ERP.

Going further, CRM will act as the leading system for the creation of all business partner master data.

My question is that if it is possible to call a java based web service after CRM transfered BP's data to ERP.

The java based web service should do the same action which was accomplished in CRM transfering BP's data to ERP.

I have the java based web service,but I don't know which CRM FM or program should be add-on.

It would be great if you can point me to the steps required for this transfer.

thanks!
