RFC
Remote Function Call (RFC) is SAP's communication interface. RFC communication
between SAP business solutions involves an RFC client and an RFC server. The RFC server
provides function modules. RFC clients call one of the function modules, pass on the data,
and get a reply (value) back from the RFC server.
Setting Up an RFC Connection
Transaction code SM59 is used to create new RFC connections or to alter an existing con-
nection. Several types of RFC connections can be set up in SAP systems using SM59 trans-
action code. RFC connection types “3” (connects to another ABAP system) and “T” (TCP/
IP Connection) are most often used.
The following procedure is used to set up an RFC connection type “3” in SAP systems.
Use transaction code SM59 in the SAPGUI command line (see
Figure 4-2
).
