How does the Include data as of date and time option affect the output?

You specify an as-of date on the Request Settings page.

The default is Now. The data export includes all eCRF data available at the current date and time (displayed in the browser time zone). Use the Include data as of date and time option to include data up to (as of) the date and time you enter. The earliest date you can select is the enrollment date of the first subject.

When you select subjects using the Export Selection Criteria option, only subjects enrolled prior to the as-of date appear in the selection list.
