The Explain tab displays an abbreviated version of the Step statistics and Explain text that result from an Explain request in an SQL session. Each Explain step is uniquely identified with a number where the background of the number box indicates status. This information is read-only. The tab is available only when a query meets certain thresholds established by the Teradata Viewpoint Administrator.
