It is conceivable that bestillingsnummer refers to a master booking, general agreement, frame agreement or similar, while ordrenummer refers to a single order for a specific item or number of items with a common delivery date and location. The latter would often be called 'avrop' in cases where a main office makes the agreement and branch offices places their orders. The precise terms are not essential here - just keeping them distinct and not confused. Booking number and order number would be a place to start. |
