You create a Session task for each mapping that you want the Integration Service to run. The Integration Service uses the instructions configured in the session to move data from sources to targets.
You can create a reusable Session task in the Task Developer. You can also create non-reusable Session tasks in the Workflow Designer as you develop the workflow. After you create the session, you can edit the session properties at any time.
Before you create a Session task, you must configure the Workflow Manager to communicate with databases and the Integration Service. You must assign appropriate permissions for any database, FTP, or external loader connections you configure.
