The scenario is the following:
1/ User enter an order based or not on a contract that specify a price with scales. From 1 to 50 unit > price A, from 51 to 100 unit> price B
The quantity defined for the special price is not totally entered in one order, but for exemple 50 units have already been ordered in previous sales document and a new order reach the quantity 51 that apply the new price.
Is there a price condition taking into account these situation of cumulative scale price?
Thank you for your help
