On the Routing tab on the Step Properties
pane, you specify any responses that the workflow participant can choose,
and the routing options for both incoming and outgoing routes.
The response the participant selects usually determines which step
executes next. See Specify responses.
The outgoing routing option determines if the work splits to two
or more routes (an AND-split condition), or if the work follows a single
route (an OR-split condition). See Specify
outgoing routing.
The incoming routing option specifies if the step acts as a collector
(an AND-join). See Specify incoming routing.
