Bump - no input?! I am disappointed in you guys!
I kid, but seriously, any input/direction would be appreciated.
I think I understand. You can do this by creating a date parameter and a calculated field. The calculation would look similar to the following:
[Date Field]>=[Date Parameter]
This can then be placed on the filter shelf and 'True' would show all the tables that have been updated since the parameter selection.
If this doesn't help, can you post a packaged workbook?
