Abstract: A system and a method for generating a purchase order allow the ordering of commodities or other parts or items electronically. The system comprises a terminal, a means for providing a graphical user interface to a user, and a server communicatively to the terminal via a network. The system and the method are used for displaying a visual of all related parts of a piece of equipment or a table of functionally related items with different specifications. The system and the method can provide time savings in viewing, reviewing, adjusting quantities, and deleting in a purchase order large quantities of related parts or items.
