On the exchange lines the part number and the quantity of the exchange is
defined as well as the type of exchange (single, double or loan). All possible
actions for the exchange are done at line level; such as dispatch and receipt of
exchange parts, scrap at customer and return of loan parts. It is also on the
exchange line level that customer approval of dispatched items and confirmation
of received items is performed.
It is possible to create new part lines for an existing component repair order
as long as the status is Released.
