About the SA System Subject Area

In Siebel Business Analytics, data visibility can be defined by the groups to which a user belongs. For example, when Siebel Business Analytics applications customers log on, the GROUP system session variable can be populated and the user sees certain subject areas and columns depending on the groups that exist in the variable. Although the GROUP system session variable provides Siebel Business Analytics with the groups to which each user belongs, it does not identify the users that are in each group.

The SA System subject area addresses this issue by exposing users in a group to Delivers. It also allows contact information such as email addresses to be retrieved from a database and used as delivery devices in Delivers. This allows Siebel Business Analytics administrators to set up the Analytics Server to automatically populate delivery devices and profiles for users instead of requiring users to update their My Account screen in Delivers.

Group membership is often maintained in an external database such as the Siebel transactional database and not in the analytics repository. This information can be propagated to the Analytics Server and Siebel Business Analytics Web Server through the GROUP session variable. The SA System subject area provides group membership and external email addresses to Delivers when used in conjunction with the GROUP session variable.
