When you specify AUTO mode, there is no background processing to start a process. The system creates the engine workfile with a request for movement, printing, or confirmation, and it processes the request automatically without user intervention.

When you specify MANUAL mode, the engine processors can process confirmation in the background, while other warehouse activity processing continues in the foreground. This is useful when you have several confirmations to process.

If you set confirmation tasks to AUTO, then use Labor Management Workbench (4.11.15) to confirm all tasks, you must wait for the workbench to confirm all tasks before you can continue processing. Even though the system processes the confirmation of each task when it creates the request using AUTO mode, processing several tasks simultaneously may take some time.
