Maintaining RFC Destinations 
From Theobald Software
To enable a call from the SAP system to an external server application, SAP must be aware of the subsystem. The subsystem is called an RFC destination in this case. A well-configured destination must be available to call a remote function module from your ABAP program.

SM59
To create a new destination, please use transaction SM59 and click the Create button. The fields have to be filled in with following values:
- Unique name of the new destination (e.g. ERPTEST)
- Connection Type = T (forTCP/IP)
- Description
- ProgramID: A unique name that the server program uses to register itself on the SAP gateway (can be the same as the destination name).
- Choose option 'Registered Server Program'
You have to save the destination first before the connection can be tested.

Click the button Test Connection while the program is running. If everything works well, you should see a screen as the one below.
