You can configure a workflow to suspend if a task in the workflow fails. By default, a workflow continues to run when a task fails. You can suspend the workflow at task failure, fix the task that failed, and recover the workflow. When you suspend a workflow, the workflow state of operation stays in memory. You can fix the error that caused the task to fail and recover the workflow from the point of interruption. If the task fails again, the Integration Service suspends the workflow again. You can recover a suspended workflow, but you cannot restart it. Configure a workflow to suspend on the General tab of the workflow properties.
You can also configure the workflow to send an email when a task suspends.
