In Oracle Order Management Cloud Order to Cash, you can set up pricing for products based on different units of measure (UOM). In this case, you would create two price list lines: one for the individual thumb drive priced at $15 each, and another for a box of thumb drives priced at $60 per box. The primary UOM check box should be selected on both lines to indicate that these are the primary units of measure for pricing12.

An attribute-to-product transformation uses transactional attributes to transform an attribute to an item number. It can add the transformation to an existing item or replace the item that the source order references.
Assume your company receives orders for an MP3 player that includes a Color attribute and a Size attribute, and that you must use a combination of these attributes to reference an item number. In the following example, a transformation rule transforms the Color and Size attributes of the Mini Plus item to the VIS481 item. Order Management displays VIS481 on the order line.
