Yes, it is possible to specify the SAP Router string in
RfcConnect, e.g. R3NAME=/H/sapgate1/S/3297/LOI
where LOI is the R/3 system name.
Please see the SAP documentation on the RfcOpenEx function for details
(file saprfc.h). GuiXT will add user,
password, client and codepage to the RfcConnect string provided in GuiXT
profile, and then perform the RfcOpenEx function.
