Configuring SNC: SAP GUI when Using SAP Logon 

Use

If you use SAP Logon to start SAP GUI, then you do not have to set up the command line yourself.

Prerequisites

The environment variable SNC_LIB on the front end needs to contain the path and file name of the external library.

Procedure

Set the SNC options (SNC name, quality of protection, SNC activation) for the application server with which you want to communicate. Make these settings in the SAP Logon Advanced Options.

There are slight differences when defining the SNC options depending on the method used to select the application server. The standard server selection methods are:

·        Manual Entry (or edit an existing entry)

·        Entry Using Server Selection

·        Entry Using Group Selection

We describe the details for defining the SNC options for each method below:

SNC-enabled logon destinations are indicated in the SAP Logon destination list using a special icon.

Configuring SNC for a Manual Entry

From the SAP Logon dialog:

...

       1.      Choose New or select the system to edit and choose Properties.

       2.      Choose Advanced Options.

The Advanced Options dialog appears.

       3.      Enter the SNC options:

                            a.      Enter (or edit) the SNC name.

                            b.      Enable SNC by activating the Enable Secure Network Communication indicator.

                            c.      Choose the Quality of Protection level that you desire (Authentication, Integrity, Encryption, Max. available).

We recommend you use the default level (Max. available).

       4.      Choose OK.

Entry Using Server Selection

After adding the server using ServersSel., configure and activate SNC in the Advanced Options dialog box in the same way as with a manual entry (see the previous section). If the server is SNC-enabled at the time of selection, then the application server's SNC name is automatically retrieved by the message server and displayed in the SNC name field.

Entry Using Group Selection

After adding the server using Groupsel., configure and activate SNC in the Advanced Options dialog box in the same way as with a manual entry. Note however, you can only enter the SNC options if SNC has already been activated for the group. In addition, although the SNC name field shows the SNC name of a server, this name is not actually used and you cannot edit it. With group logons, the application server's SNC name is dynamically requested by the message server each time a SAP GUI connection is started.
