These steps assume you performed the Export function on the Manage Workflow Templates page in Rival WingSpan.
From the navigation bar, click Administration.
From the Settings page under System Management, click Import.
Verify the name and date/time of import matches the exported workflows.
Click Import. The reviews are imported and are shown on the Review Process page as Closed.
