Role. A KFS user role that allows for document approval at any route level (including Ad Hoc Routing). As a document moves through Workflow, it moves one route level at a time. An approver operates at a particular route level of the document. The first route level for most financial documents is the Fiscal Officer route level (also called the Account Level). The screen view and available action options of a document may vary, depending on whether the document is at that approver's route level, or at some other route level.
