Maintaining CPIC Destinations and Their SNC Options Using Transaction SM54

Use transaction SM54 to configure CPIC destinations for SNC protection.

When maintaining the SNC options for CPIC destinations using transaction SM54, you specify the following SNC information:

• SNC mode for the connection (active or inactive)
• Quality of protection (QoP)
• SNC partner name

The other SNC-relevant settings (the application server's SNC name, the location of the external library, the maximum quality of protection, and the default quality of protection) are applied as defined in the application server's instance profile (see Profile Parameter Settings on AS ABAP).

• SNC is activated on the application server.
• The CPIC destination has been defined.

From the Maintain Table TXCOM screen (transaction SM54):

1. Place the cursor on the destination application server and choose the symbol for Change.

   The Change XCOM Entry screen appears.

2. To activate SNC for the CPIC destination, enter ON in the SNC Mode field. (Enter OFF to deactivate SNC).
3. Choose the symbol for SNC attributes ().

   The Change View "SNC extension": Details screen appears.

4. Enter the quality of protection in the QOP field and the SNC name of the communication partner in the SNC name field.
5. Save the data.

The following rules apply to the relationship between the QoP entered in the above screen and the QoP that exists in the application server's profile parameter:

• If the CPIC destination's QoP is larger than the level provided by the external security product, then the largest possible QoP is used.
• If the CPIC destination's QoP = 8 (default), then the QoP value from the application server's snc/data_protection/use is used.
• If the CPIC destination's QoP = 9 (maximum), then the QoP value from the application server's snc/data_protection/max is used.
  Note

  Set the QoP to either 8 (default) or 9 (maximum value).
