SAS Web Report Studio 4.2 provides you an excellent interface to schedule reports to refresh, because why would you want the report to generate for every user every time they open the report when the data is only updating weekly/monthly/etc?

During your design and development of these scheduled reports, consider two items:
1. Further analysis/drill steps that users take:
If you would like to drill into the data further you will need to refresh the screen. Included is a reference to the consequences - note that scheduled reports are considered those with 'Data can be manually refreshed'.

2. Prompts:
Also, if the report has multiple prompts available, you will need to schedule these individually. An example of the prompt screen is on the page: http://support.sas.com/documentation/cdl/en/citug/61084/HTML/default/p0kwc2zc67df4kn1lhqdvbxyuh72.htm.
