Add a gateway element to your process
diagram to execute branches in parallel. When you add a gateway,
it contains one branch and no other elements. You can add elements
and additional branches as required. You can rename or add a description
to the gateway to distinguish it from others in the process diagram.
Note: You cannot add gateway elements to short-lived
processes. If a branch within a gateway is transactional, you cannot
add a gateway to it. However, you can add a gateway to a main branch
that is transactional. (See Branches.)
You also configure when the main branch proceeds after the gateway
element is executed. The Control Type property controls this behavior,
and can be set to the following values:
- AND-WAIT:
- The main branch proceeds after all of the branches in the
gateway are complete. AND-WAIT is the default value.
- OR-WAIT:
- The main branch proceeds after only one of the branches in
the gateway is complete.
- NO-WAIT:
- The main branch proceeds immediately after the branches in
the gateway are started. The main branch does not wait for the branches
to complete.
You can delete the gateway element from the process
diagram at any time. When you delete a gateway element, all routes
to and from the gateway element are deleted. All branches in the
gateway are also deleted.
To add a gateway element:Drag a Gateway  from
the toolbar to a location in your process diagram. If the process
is short-lived, you are prompted to change it to long-lived.
(Optional) In the Gateway Properties dialog box, provide
a name and description:
In the Name box, type a name
for the gateway element.
In the Description box, type text to describe the gateway
element.
In the Control Type list, select the control type to use.
Click Save.
To delete a gateway element: In the process diagram,
perform one of the following tasks to delete a gateway element: Right-click the gateway element and select Delete Gateway.
Select the gateway element and in the toolbar, click Delete  , press
the Delete key, or select Edit > Delete.
