Sample entry in the sideinfo file:
DEST = RFCEXT
GWHOST = <host name of the SAP gateway, e.g. hs0311>
GWSERV = <service name of the SAP gateway, e.g. sapgw53>
PROTOCOL = <C/E (or R): server will be started by (or is already registered at) SAP-GW>
LU = <host name of the RFC server program, e.g. hs0311>
TP = <name of the RFC server program, e.g. /rfctest/srfcserv>
Moreover, the parameter mode in RfcOpen must be set to RFC_MODE_CPIC.
With the entry above, no entry is necessary in the sideinfo file for the SAP gateway.
