In the context menu of a process, choose Open .
Expand Flow Objects from Palette .
Choose a gateway from the dropdown menu, containing all the gateways, and click the modeling surface.
The gateway appears in the place you clicked.
Choose General in the Properties view and specify a name of the gateway in the Name field.
