You have been asked to revise a SQL Server Integration Services (SSIS) package. The package only includes Execute SQL tasks. To make sure that, in the event of an Execute SQL task failing, changes mad

NotSupported means the package explicitly opts out of transactions entirely, so no rollback mechanism exists if a task fails.

Supported means the package will join an existing ambient transaction if one is present, but will not start its own - leaving no rollback guarantee when the package runs standalone.

NotRequired is not a valid value for the TransactionOption property; the three valid enumeration values are NotSupported, Supported, and Required.

When TransactionOption is set to Required, the SSIS package starts a distributed transaction and all child tasks that support transactions enlist in it. If any Execute SQL task fails, the entire transaction is rolled back - undoing all changes made by every task - because Required is the only setting that guarantees atomicity across the package.
