A workflow must contain a Start task. The Start task represents the beginning of a workflow. When you create a workflow, the Workflow Designer creates a Start task and adds it to the workflow. You cannot delete the Start task.

After you create a workflow, you can add tasks to the workflow. The Workflow Manager includes tasks such as the Session, Command, and Email tasks.

Finally, you connect workflow tasks with links to specify the order of execution in the workflow. You can add conditions to links.

When you edit a workflow, the Repository Service updates the workflow information when you save the workflow. If a workflow is running when you make edits, the Integration Service uses the updated information the next time you run the workflow.

You can also create a workflow through the Workflow Wizard in the Workflow Manager or the Workflow Generation Wizard in the PowerCenter Designer.
