Use a Wait element to specify a wait condition based on a unit of time or a duration.
Drag the Wait element from the Palette to the diagram. Like other elements, it must be placed in the correct position in the process flow; otherwise you will not see the element in the diagram.
Right-click the element in the diagram and choose Properties to invoke a Properties window. Using the Properties window, you can specify:
The name of the element.
The alarm type. The available options are:
For – specifies a duration for the process to wait
Until – specifies the time until which the process is delayed.
For/Until. Clicking the ellipsis button (...) invokes a dialog box where you specify the time in accordance with the selected expiration type.
