You are editing a SQL Server Integration Services (SSIS) package that contains three Execute SQL tasks and no other tasks. The three Execute SQL tasks modify products in staging tables in…

When a package's TransactionOption is Required, SSIS starts a distributed transaction at the package level. Child tasks with TransactionOption set to Supported automatically enlist in that ambient transaction rather than starting their own. If any of the three Execute SQL tasks fails, the single encompassing transaction is rolled back, undoing all three tasks' changes atomically.

Setting all three tasks to Required would cause each task to start its own independent transaction, so a failure in one task would not roll back the others.

A Foreach Loop container provides looping logic but does not create or manage a transaction scope and has no effect on rollback behavior.

A Sequence container is used for grouping and precedence control only; it does not create a transaction unless its own TransactionOption is explicitly set.
