The Kit header has a price and all components are delivered but the invoice total is 0.00

Problem

A kit with a selling price has been added to a sales order and the components are delivered in full but the invoice total is 0.00.

Solution

Kit and component pricing requires a Default selling price for each component, even if its one cent.  The formula that is used is a weighted average of the total price for each component as a percentage of the kit header price.  Each component price is then adjusted so the total of all the component lines' prices agrees to the kit header price.
