When a queue is configured with the Auto-Feed option, locks are placed on work items. When the user first opens the auto-feed queue they are displayed the first available item in the queue. The item has an auto-feed lock placed on it which can be viewed by selecting Admin | Utilities | Process Lock Administration in the OnBase Client.
The purpose of the auto-feed lock is to prevent another user processing the same queue from processing the same item. When the user selects the Show All Documents right-click option, the Auto-Feed lock is removed from the item currently displayed and the inbox displays a list of all the items in the queue. When the user selects an item, no auto-feed lock is placed on the item. It works as though the queue never was configured for Auto-Feed.
