Designing Processes › Process Lanes › Lane Handling Rules

Lane Handling Rules

When a process contains multiple lanes, you can define lane change rules. These rules specify operator sequences that are invoked only when running a process crosses a lane boundary. Each rule is defined to occur for one of the following lane transitions:

• From a specific lane to another specific lane (from lane A to lane B)
• From a specific lane to any other lane (lane A to any)
• From any lane to a specific lane (any to lane B)
• From any lane to any other lane (any to any)

Lane change rules look like any operator sequence on the Main Editor tab, except each rule starts with a Lane Change operator instead of a Start operator. Lane Change operator properties define the transition between source and destination lanes that invoke the operator sequence that is linked to the Lane Change operator.

Follow these steps:

1. At the bottom of the Process Designer, select the Lane Change Handler tab.
2. From the Operators palette Standard group, drag a Change Lane operator to the Lane Change Handler panel.
3. Double-click the Change Lane icon, and click the Properties pane Change Lane properties panel.
4. In the Name field, type a name to identify the rule.
5. For Source and Destination, select the combination of lanes that triggers the rule.
6. Click Apply.
7. From the palette, drag more operators to the process that completes the rule for the transition, and configure each one as necessary.
8. In the toolbar, click the Save button.

   The new transition rule is complete.
