SNC Authentication

This page shows how to configure the Xtract data source to use encrypted communication via Secure Network Communication (SNC) between Xtract for Alteryx and SAP.

Prerequisites

• Secure Network Connection (SNC) is configured in your SAP system, see SAP Help: Configuring the Application Server.
• Download the same SAP Cryptographic Library that is used for the encryption in your SAP system (sapgenpse and sapcrypto.dll) from the SAP Service Marketplace. To check which library is used in SAP, go to transaction RZ10 and check the SAP profile parameter snc/gssapi_lib in SAP transaction RZ10.

Secure Network Communication (SNC)

Follow the steps below to set up SNC credentials for an SAP connection:

1. In the main menu of the Alteryx Designer navigate to File > Manage Connections. The window “Connection Manager” opens.
2. In the tab Credentials click [New] to create a credential.
   
3. Enter a name for the credential, e.g., "alice-SNC".
4. Select the authentication method SAP SNC.
5. Enter the SAP Partner Name configured for the SAP application server in the field Partner Name, e.g., p:SAPserviceERP/Alice@THEOBALD.LOCAL.
6. Enter the path to the SNC library in the Library Path field, e.g., C:\Program Files\SAP\FrontEnd\SecureLogin\sapcrypto.dll.
   
7. Click [Save] to save the credential.
