Interfaces to External RFC Programs
The SNC configuration for external RFC client programs is located in the saprfc.ini file. For an RFC server program (for example, a program started from a gateway), the SNC parameters are passed to the server program from the client. (For information about starting external RFC programs, see:
- RFC: TCP/IP Connection - Start an External Program on an Application Server
- RFC: TCP/IP Connection - Start an External Program on an Explicit Host
- RFC: TCP/IP Connection - Start an External Program over SAP GUI
- RFC: TCP/IP Connection - Registered Program
You can alsospecify the parameters from the RFC interface using the function
RfcOpenEx Open an RFC connection (SNC parameters are specified in the connect_param string)
You can use the following functions to obtain SNC information:
