Order should not appear in V.23

Hi All,

We have a return process, where we create a return order on UNKNOWN customer and do the delivery, in a situation where sold to and ship to are not confirmed for the order.This will be not relevant for billing(setting in item category) and again,it will be shown up in V.23. Then,we create a original order with real sold to and ship to with reference to the order created on UNKNOWN customer,and it is not relevant for delivery,release billing block in V.23 and creates billing,

My REQUIREMENT is whenever a original order is created with reference to Unknown order, the order with UNKNOWN customer should not appear in V.23.Can somebody suggest on this?
