Establishing an RFC Connection to SAP Systems

Contrary to SAP R/2 (IBM), the SAP gateway does not need a specific entry in its sideinfo file if all needed parameters are specified in the local sideinfo file or if they are defined in the RFC client programs.

An RFC client program can work

with a local sideinfo file (see Programming Example of Working With Local sideinfo file)
without any local sideinfo file (see Programming Example of Working Without Local sideinfo File)
with the saprfc.ini file (see Programming Example of Working With saprfc.ini File)
