Set Up an RFC Destination

To enable calls from an SAP system to a subsystem, the subsystem must be known to SAP.
This can be done with an RFC destination. An existing RFC destination is necessary for sending IDocs.

To set up an RFC destination in SAP:

1. Use transaction SM59 to create a new RFC destination.
2. Fill the following fields of the destination:
   
   • Unique name of the new destination e.g., ERPTEST.
   • Connection Type = T (for TCP/IP).
   • Description.
   • ProgramID: A unique name that the server program uses to register on the SAP gateway.
   • Choose the option Registered Server Program.
3. Save the destination.
4. To test the RFC-Destination, click the button [Test Connection] while the program is running.
   If everything works well, you should see a screen like the one below:
   

The RFC destination is ready to use.

An example for a simple RFC server program can be found in section RFC-Server
