To convert the 'Not-Sold' items into inventory...
The inventoried items can now be pulled up on the clerking terminal by entering the item number in the item field on the terminal.
Items that are converted from 'Not-Sold' items into inventory cannot be grouped (1--5, 1-5, 1-5@, etc) until you exit to the main menu and re-enter the current auction.
If you exit the current auction and attempt to re-enter the current auction you may see a message stating 'Optimize inventory'. Simply go into the inventory area and exit to the main menu. You will then be able to re-enter the current auction.
