CPIC: Registered Program 

Use

CPIC registered programs are saved in the table TXCOM with type = R. For a CPIC call that starts a registered program, the calling AS ABAP is the initiator of the communication and the registered program is the acceptor.

Initiator (AS ABAP)

To specify the SNC options for the initiator (AS ABAP), use transaction SM54. See Maintaining CPIC Destinations and Their SNC Options Using Transaction SM54.

Acceptor (Registered Program)

The SNC options as entered in SM54 for the initiator are automatically sent to the program to be started. These options include the SNC mode (active or inactive), the SNC name for the external program (SNC partner name), and the quality of protection.

To specify the path and file name of the external library, the gateway that starts the external program sends the value of its own profile parameter snc/gssapi_lib to the external program as a command line parameter. (The command line parameter value overrides the SNC_LIB environment variable.)

Because the registered program needs access to the external library, and the gateway provides its location, you can only use SNC protection for registered programs that are started on the computer where the gateway is located.

Gateway Operations
