To start the Batch Executive, the user must have access to the Start menu on the Windows desktop. The DeltaV security system prevents users who do not have either Windows Administrator privilege or the DeltaV "Can Configure" key from accessing the Windows Desktop. Therefore, a user must have one of these privileges as well as the key that is assigned to the Batch_Control_Start and Batch_Control_Stop function locks in order to start and stop the Batch Executive.
