This produces an exception report, which checks for data integrity of the Siebel Data Warehouse. This should be run before running Full_Load_Siebel_DW or Refresh_Siebel_DW. The results of the exception report can be used to make necessary corrections to the Siebel Transaction Database.
When this batch process completes, you can view the results in the Siebel Analytics' Analytics Administration view. For more information, read Using the Exception Report and Diagnostic Views.
