When you execute a query with Resource Manager restrictions in the VDP Administration Tool you can check the State value of the Execution Trace tab. In that value, when a Row limit restriction has been aplied, the ROW\_LIMIT\_REACHED status is shown.
For those specific scenarios where you want a query to be rejected depeding on different conditions such as the row number, you can develop a custom policy. Check the [Developing a Custom Policy](https://community.denodo.com/docs/html/browse/7.0/vdp/developer/custom_policies/developing_a_custom_policy) section of the VDP Developer Guide for more information.
Hope this helps!
