The default queue on a server is the queue to which batch jobs are submitted when the user does not explicitly request a queue. The default queue cannot be a remote queue; it must exist on the server.
Manager privileges are required to set a default queue.
Using Project Management:
In Project Management, right-click the model and select Configure Queues for Jobs.
The Configure Queues for Jobs dialog box displays.
Type a queue name into the Default Queue box, or select a queue from the dropdown list.
