Reports are generated during beginning-of-day (BOD) processing and end-of-day (EOD) processing seven days a week.  No configuration changes are needed.
 
A whole new set of reports will be created on Sunday as with Saturdays.  If you refer to reports daily, you will also need to review the Sunday reports, in addition to Saturday reports, if you do not already do so. 
 
Refer to the documentation on daily CU*Spy reports for more assistance.
