The SAP Gateway and The SNC Interface


As of Release 3.1G, communication is secured by the integration of the SAP SNC interface (Secure Network Communication).

SNC supports third-party security systems (such as Kerberos, SECUDE, etc.). This provides for a reliable authentification of the partners and secure data transfer.

The SAP Gateway can reject connections that are not based on SNC.

You can set a number of SNC parameters (see the parameter documentation using Transaction RZ11, snc*).

For the SNC function calls of the CPI-C library, see the documentation SAP Communication: Programmer's Guide

If a user wants to communicate using the SNC interface, the following prerequisites must be met:

  1. The user has logged on to the security system
  2. An SNC name and the SNC library have been defined using Side Info Parameter or Environment Variables.
  3. The SAP Gateway supports SNC and has been started using the system profile parameter snc/enable.
