SAP PI to Data Services (BO)

Hi,

We have an existing interface in R/3 which directly communicates to Data services via idoc.

We are trying to bring in PI to be used as ESB into the landscape.

Can PI connect to Data services via Idocs?

What config would I be required to do on R/3 and PI side.

We are thinking of using PI 7.3.

Regards

Krish
