One entry in a component's Part Choice list: a manufacturer part, rather than a specific supplier, that may be used to implement the component, bringing with it the offers of the suppliers that sell it. Entries are ranked automatically by availability, price and lifecycle, and users can override the order with their own rank; the top preferred entry is used as the component's part choice in a BOM.
