Customer Order

A customer order

Changing of the customer order

Changes (as possible with internal orders) are not permissible as a PO/CO-pair are a legally binding entity, and require mutual consent. So in the UI changing and change requests are permissible, but in the data model the offer-process has to be employed to reach a new PO/CO-pair are descendant of the old pair.

As a result, when a change was accepted, a corresponding offer has to be sent to the customer, which then accepts the offer, which results in a contract, which results in a new PO to be sent to the suppler, which then becomes auto-accepted.
