# Marking records Verified or Not Verified in the Data Viewer

Note: You can also mark forms as Verified or Not Verified from a CRF. For more information, see Source verifying data on an online form.

1. Navigate to the Summary View, Record Listing View, or Record Comparison View in the Data Viewer.

   For more information, see:

   - Displaying the Summary View.
   - Displaying the Record Listing View.
   - Displaying the Record Comparison View.
2. Click in one or more data cells in the data table to highlight the records.

   The level of records (visit or form) that are available to be marked as verified or not verified depends on the view you select.

   - Summary View—Visit or site level.
   - Record Listing View—Visit and form level.
   - Record Comparison View—Visit and form level.

   For example, when you are viewing data in the Record Listing View, you can mark as Verified or Not Verified selected forms, or all forms under selected visits.

3. For a form or forms, in the toolbar, from the Source Verification drop-down list (), select Mark Verified or Mark Not Verified.

   A progress indication appears. An error message appears if there are any failed actions.

   or

   For a custom view, in the toolbar, from the Source Verification drop-down list (), select Mark item verified or Mark item not verified.

   Because a custom view is created from multiple clinical forms, you can apply verification only on the selected items in the Record Listing View or Record Comparison View.
