Gateways (BPM)
Go Up to Business Process Modeling Elements
A Gateway controls the divergence and convergence of the Sequence Flow. It determines branching, forking, merging, and joining of paths. Basically it is a question that is asked at a point in the flow. This question has a defined set of alternative answers.

|
This symbol displays decisions, merges, forks, and joins in the process flow. It controls how Sequence Flows interact as they converge and diverge within a process. You can set the Gateway Control Types of a gateway and change the logic specified by it. There are two different ways to set the Gateway’s control types: from the palette, or on the Model View. |
Placing Gateways Using the Palette
- 1 Click Gateway in the Business Process Objects Palette to expand the node.
- 2 Click the gateway with the control type you want to use from the expanded node.
- 3 Click once in the Diagram View and the selected gateway is placed in the diagram.
- Note: Notice that the selected gateway also appears in the Model View tree with the appropriate icon designating the control type.
Placing Gateways Using the Model View
- 1 Right-click the lane name where you want to place the gateway.
- 2 Select New and then select Gateway from the list of available elements and a gateway node is placed in the Model View tree.
- 3 Double-click the gateway node and the Gateway Properties View opens.
- 4 In the Type list box select the control type you want to use from the type drop-down list and click OK. The gateway node icon changes to represent your control type.
- Note: You can then drag the gateway node from the Model View tree on to the Diagram View.
