The Index Impact Analyzer Scenario can be re-executed using the same indexes. You can choose to retrieve the query plans for all SQL statements in the Scenario or select specific SQL to retrieve the query plan again using the same indexes. This function is useful if changes have occurred in the database environment, such as data volume changes, that may affect query plans.
