The 4.2 version of SAS Information Map Studio provides data managers with the ability to create a dynamic filter based on dates. This is extremely valuable for things such as daily reports.
Included below is an example of a new filter that is built off a date formatted data item.
You are then allowed to select a parameterized date, such as Today, Tomorrow, or Yesterday.

Also note that I also circled the 'Hide from user' box. If you don't select this item, the WRS authors have the ability to choose whether or not to include this filter. However if you DO select this, ALL data out of this information map will be filtered accordingly. (In this situation, I always modify the name of the information map to make it apparent that a filter occurs.)
