Flow Control

The Decision shape is used to express alternative paths of execution in a business process. The shape is used to define the flow of control in the schedule. You can use this shape to check the value of a message field and choose a specific path based on that value. This checking is done using rules.

The Decision shape can contain one or more rules in addition to the default clause Else. The rules in the Decision shape are evaluated sequentially. The first rule to evaluate to TRUE determines the path taken by the business process flow. The default rule clause, called Else, always evaluates to TRUE and is the path taken if all previous rules return FALSE.
