Database Multi-Connect 
In this scenario, the source Web
Application Server accesses a remote SQL Server database via multi-connect.

The following features apply:
-
PRD can be an SAP ABAP database, the database of an SAP Java
application or any other SQL Server database
-
PRD must be a SQL Server system (SQL Server 2000 and
higher)
-
TST may use any database platform, but SERVER1 must run on
Windows. If TST is a non-SQL Server system, you need to use transactions
ST04_MSS, DB02_MSS and DB12_MSS instead of transactions ST04, DB02 and DB12.
-
In contrast to the RFC scenario, some monitor functions are
not available
