The **Apply Numbering Scheme **functionality allows the numbering along a flow path to be set for the connections and/or junctions. This option is only available to a Flow Path that begins at a node that does not have upstream items, that is, no incoming connections (inflows are permitted).

When you click **OK**, InfoDrainage will renumber from the head of the flow path down to the end with any incoming branch lines numbered in turn.
