Routing

Routing The Routing task implements a branching function. This task, and associated outbound transitions can be used to create simple programming logic similar to if, then, else and switch statements. For further details on how to configure a routing task, see Creating a Workflow Process

Duration
This can be set to a specific time or determined by a date index field. It determines the time after which the task will become overdue. It can then be used in conjunction with an escalation transition. See:
Properties

Edit
Opens a dialog where it is possible to configure the error handling. If the checkbox 'Treat as error if no valid transition is found is checked', then the workflow will immediately be canceled and an error will be logged.  If the routing task should wait for a certain index value to become valid, then this box should not be checked.  

Note: A single routing task can support multiple transitions to other tasks. However, conditions must be set so that only one condition is valid at the time the routing task is executed. Otherwise, the task will result in an error.
