Change net price and net value in sales order after billing process
I'm having a problem, after creating a sales order with two or more items and complete the sales flow (sales order, delivery and invoice) of one of them to return to sales order and modify and save the delivery date item not yet billed, the net price and net value change automatically.
I'm not using either solution "Z"
