Hi Experts:
Our BASIS team added 2 ECC 6.0 Source Systems to BI 7.0. One of the ECC 6.0 System is added under BI Folder ( where DataMart Source stays) and other ECC 6.0 system is added under SAP folder where all other R/3 Source Systems are. I talked to BASIS team and they followed the same configuration in SM59 for both of the RFC connections.
Other peice of Information, Both the ECC 6.0 systems are on same server but just different Client.
This is how it looks:
RSA1 -> SOURCE SYSTEM
-> BI Folder - 1st ECC 6.0 System
-> SAPFolder - 2nd ECC 6.0 System
Thanks,
Rez
