This structure provides a connection to an R/3 System. The target system must be Release 3.0C or later.

typedef struct {
char * hostname;
RFC_INT sysnr;
RFC_INT use_load_balancing;
char * lb_host
char * lb_system_name;
char *lb_group;
RFC_INT use_sapgui;

Since an R/3 System of version 3.0 always has its own ‘gateway’ process, no gateway options are necessary any more.

This structure is defined in SAPRFC.H.


Starting sapgui takes some time, so you should not set that value if you do not need it.

This field is set automatically as soon as you activate the ABAP debugger by entering ‘d’ in the trace field or by setting RFC_DEBUG in the system environment.
