On the Routing tab on the Properties pane, specify the routing options for both incoming and outgoing routes.
If the current step will act as a collector step (an AND-join) for a previous AND-split step, select Collector Step under Incoming Routing Information; otherwise, clear the Collector Step checkbox. See Create a valid workflow map for information about using AND-join and AND-split steps.
To see any conditions specified for a route, select the route and click Details.
This creates an AND-split; you must specify a corresponding AND-join for a subsequent step. See "Specify incoming routing" (above) for information about creating a collector step (AND-join).
