This KB article contains fixes for the following issues.
The following errors correspond with the issues stated above:
The stored procedure spITAnalytics_SEP_Createviews runs each time you add a SEP database connection to create the various views required to populate the cubes from the SEP databases. It makes a check to verify the SEM_SVA table that is listed in the error message exists. If that table exists then it should create two views that read data from that table. The error message occurs when it attempts to add the two views and fails to find the SEM_SVA table
You should now be able to process cubes without the above errors.
Note: This issue has been resolved in newer versions of this software and this solution should not be applied to these newer versions.
