The Validation Manifest allows the user to select a grid, and then add rules to validate the content of the grid. There are different available rules for any given type available in the grid.
Validation Manifest Editor

If you want to validate the fact that the grid is empty (for example, because your query only returns rows that fail) you can select the 'Only pass validation if no rows are present' option.

Comparison Value - The comparison value is compared to the row of each column using the previoulsy selected Comparison Type.
Cancel - Will cancel out of the new comparison wiithout saving.
Add - Add will be enabled once all fields are populated for the new rule. Clicking add will save the rule to the Validation Manifest.
