Can I change the product quantity of a schedule in EBS and keep the same order number?

If the intended procedure is to reduce the product quantity of an order, we must check whether it has more than one product type. With only one product type, we can reduce the quantity and keep the same order number; if there are two or more, we must cancel it and create a new order.

If the procedure is to increase the quantity, regardless of the product types, the order must be canceled and a new one created with the requested quantity.
