Parts Dashboard catalogs the different things that you want to keep track of. These things are called “Items”. The primary categorization of Items is into Item Types.
Parts Dashboard come pre-loaded with some default Item Types, such as Document, Inspection, Operation, Part, Project, Raw Material, etc.. Each of these types is configurable from within the Item Types tab of the System Configuration window, and you can create new Item types here also.
To view or edit an existing Item Type, select it from the drop-down at the top of the window.
To create a new Item Type, hit the plus button next to the selector drop-down, and type in the name for the new Item Type.
See here for more info on Item Types.
