Establishing an RFC Connection to R/2 Systems

Establishing an RFC connection to an R/2 System in an SNI environment is similar to an SAP system, except that the SAP gateway must run on a BS 2000 host.

Therefore, the following sections contain descriptions on establishing RFC connections to R/2 Systems in IBM environments.

A sideinfo file for the SAP gateway is always required.

The 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)

The following sections describe only how to establish an RFC connection to R/2 Systems with ConnArgv. For information about how to establish an RFC connection to R/2 Systems in the subroutine RfcConnect, see ‘srfctest.c’ in the RFC SDK.
