We have an item with first demand on 8/3, and a 63-day lead time, so MRP schedules the WO to start on 6/6. The issue is that it starts generating Planned Transfer Orders from that supply immediately on 6/6. We pick up full production from our manufactures on completion, so inventory from a WO shouldn't be available until it's fully completed (in this case, 8/3). Important note: not using WIP I feel like i'm missing something really simple here.
