This feature supports to have delivery dates recalculated for sales order lines with CTP as delivery date control while keeping CTP as order line delivery date control. Without this feature, changes on the sales order header requiring a recalculation of delivery dates for lines with CTP as delivery date control, will always change the line delivery date control for these lines from CTP to None. With this feature it is also supported to create lines through 'Add from products' and 'Add from item list' in combination with CTP as delivery date control.
