External External program program
For an RFC connection, you need to make the appropriate entry in the table RFCDES with Transaction
SM59.
Since the SAP gateway uses the values in TXCOM or RFCDES, you do not need an entry in the side
information table. The external program is started via the SAP gateway.
A distinction is made as to whether the SAP gateway runs on the same machine as the external program
or not.
SAP gateway and target machine identical:
The SAP gateway has a particular ID which corresponds to the user name (c11adm) used to start it.
==> The external program must be in the user’s search path and able to be started with this ID
SAP gateway and target machine different:
The SAP gateway starts the external program with Remote Shell or Remote Execute. Also, the above user
must be known in the target system and have an entry in the .rhost.
