Can one NetWeaver 7.0 (2004s) BI Portal handle multiple NetWeaver 7.0 (2004s) BI systems?
Each NetWeaver 7.0 BI system needs its own BI Java usage type which again needs its own EP usage type. That means you can bring different BI systems together in one overall 04s or 6.0 EP but technically each NetWeaver 7.0 BI instance also has its own EP installed underneath for technical reasons. For endusers of course you bring it all together in one EP on top.
