Job B: In case JOB A fails, Job B will be executed instead. when it will commit. You can build event handlers for packages, the Foreach Loop container, the For Loop container, the Sequence container, and all tasks. To add execution logging to any SSIS package: Delete the demo tasks from the demo sequence container. A Foreach Loop container is like a For Loop container but differs when it comes to the number of times the loop executes.
