The Scenario can be re-executed using the exact same logon and configuration parameters. You can choose to retrieve the query plans for all SQL statements in the Scenario or select specific SQL to retrieve the query plan using the same logon and configuration parameters.
The function is useful if changes have occurred in the database environment, such as data volumes, that may change the query plans.
To regenerate a Scenario
Select the Scenario you want to modify from the left pane.
