Reservationer og ordresporingskæder brydes , hvis en situation bliver umulig som f.eks at flytte behovet til en dato før forsyningen . Ordre-til-ordre-link tilpasses dog ændringer i de respektive udbud eller efterspørgsler , og dermed afbrydes forbindelsen aldrig .

Reservations and order tracking links will break if a situation becomes impossible , such as moving the demand to a date earlier than the supply . However , the order-to-order link adapts to any changes in the respective demand or supply and thereby the link is never broken .
