A single rule serves as an exclusive split. A rule is used for simple condition checking in a business process. A rule is a logical expression, for example a > 5. A rule is either true or false and there is only one path that the processing can follow based on the results of the condition at runtime.
Create a single rule using the Logic Tool Palette from the Business Process Editor canvas.
To create a single rule:
From the Logic Tool Palette, drag and drop the Single Rule icon onto the canvas.
To rename the rule from its default name, do one of the following:
Click in the rule's current label and type the new name.
In the rule's associated property sheet, go to Diagram -> Label, click in the Value field and type the name.
Double-click the Single Rule icon to open the Rule Builder.
The Rule Builder opens.
Follow the steps in Building a Business Rule to define your rule.
