BW Role Menu - Portal Integration

Hello everyone,

We would like use the role menu (BW 3.5 & EP6 SP9) as an iview in the portal. The connection between Portal and BW would be done via user mapping with 1 SAP ID for all portal users. The set-up of the BW web template is that we left the role menu in the properties of the role menu blank. By leaving it blank it pulls in all the queries and web templates published to it. Now we want to filter the role menu based on portal role. Is this possible and if so how to achieve this? Note the portal users do not have BW ID's as we are using 1 SAP (generic)for connection to BW.

Thanks,

Gary
