WS-RM integration with FSCM on one side

Hello All,

We are planning to integrate SAP FSCM Credit Management with SAP ECC through standard SAP PI interfaces using recommended WS-RM functionality. I understand that WS-RM is supported only from SAP PI 7.1 and SAP ECC 6.0 EHP 5 versions onward.

The SAP FSCM system in our landscape is above EHP 5, however the SAP ECC system is only on EHP 1. Would it be possible to have SAP PI interfaces having WS-RM connection wirth FSCM system (> EHP 5) and ABAP proxy integration with SAP ECC (< EHP 5)?

Thanks in advance for your replies.

Regards,

Rosie Sasidharan.
