Configuring BPM with the UWL

Hello Experts,

I need to set up an Universal Work List on EP server to list all the Tasks and Process including BPM based ones...

Part of Landscape is; we have an SRM Portal Working on SRM ECC, a BPM server (Which is my side basicly) and an EP Portal Server.

Basic scenario is; Customer will logon to EP server(single sign-on with other systems), will fill up the shopping cart(SRM) and depending on the total price diffirent approval processes (BPM) and after approval the process will continue..

Approvers also will use EP server to complete theirs tasks which were triggered from BPM.

So, how am i going to configure EP UWL to show tasks from BPM, i have been through this link; http://help.sap.com/saphelp_nwce72/helpdata/en/0e/57827af0e34edfacd4c82edeb6acca/content.htm

But my question is; on the consumer part (which is EP) how am i going to connect to BPM (as a Portal server) from EP? It only decribes the connection as a R3 system but BPM is only a java portal system. I couldn't manage to connect from EP to BPM, is there any way to connect from portal system to portal system or is there any other way achieve this ?

Any suggestion will be appreciated.

Thanks,

Yasin
