A Queue is a way to organize cases (containing batches and documents) into a list accessible by users at different points in a workflow process. As cases move through a workflow process, they will flow into a Queue to have some kind of task or knowledge work performed by a user. When the user has finished the appropriate tasks at that step, the case is "Completed", causing it to move to the next step in the workflow process.
A Queue can be accessed at any time from the Case Toolbar, using the Queue drop down and the Queue Case List button. You will only be able to see the Queues for which you have been granted access by a System Administrator. Click on any case in the list in order to open it.
The Local Queue is a private queue that is associated with your login and only you can see. The Local Queue is accessible from the Queue Drop Down, and new batches will be listed in the Queue Case List for the Local Queue. All new batches are placed in the user's Local Queue when they are created. In order for a batch to be started into it's workflow process, it must be completed from the Local Queue.
