MRP - How to exclude demand of a component based on parent WO's routing status

Is there a way to exclude requirements for a component if the parent's WO has already completed the operation step that requires the component, regardless whether or not the component is issued to the WO?  E.g. If Parent ABC's Operation Seq #50 requires 5 pcs of Component 123.  Upon completion of Oper Seq #50 (i.e. Status = 30), MRP will exclude the 5 pcs requirement for Component 123 even though the 5 pcs have not been issued to the job.
