    Note

    NOTE: This feature is in Beta release.

    • Enhancements include:

      • Drag and drop to reposition objects on the Flow View canvas, and zoom in and out to focus on areas of development.

      • Perform joins and unions between objects on the Flow View canvas.

      • Annotate the canvas with notes.

    • You can toggle between new and classic views through the context menu in the corner of Flow View. See Flow View Page.

      Note

      Flow parameters do not apply to datasets or output objects, which have their own parameters. However, if you specify an override at the flow level, any parameters within the flow that use the same name receive the override value, including output object parameters and datasets with parameters.

    • See Manage Parameters Dialog.

    • For more information on parameters, see Overview of Parameterization.
