SAP system landscape. Please note that a successful authorization test is mandatory, as this
test executes a user login along with password verification and authorization test in the tar-
get RFC-connected system. A successful authorization test ensures that the RFC connection
is completely ready for use in an application.
Several other RFC connection types are used to integrate the SAP system landscape. The
RFC connection type “T” refers to starting an external program using TCP/IP. One example
of such need in a SAP system landscape integration scenario is within the SAP Process In-
tegration application. In this scenario the Process Integration (PI) ABAP components integ-
rate with the SAP PI Java component using this connection type.
The SAP PI ABAP system integrates with the SAP Java-based PI component referred to
as the System Landscape Directory (SLD) using an RFC connection called SAPSLDAPI.
Figure 4-6 shows the details that have to be entered in setting up a TCP/IP RFC connection
type. In this type of connection, a registered server program ID is entered in the RFC con-
nection on the ABAP side, and the exact same entry is made in the JCO RFC provider ser-
vice on the Java side. Once the settings are complete, the connection test can be executed.
