I have a product that we buy the materials from, then manufacture and then send it out for finishing. 

I am having a hard time figuring out how to configure the last PO after manufacturing, so far i am only able to get it to generate a PO for the materials and the Manufacturing order. 

My goal is to have this happen:

New SO -> PO (raw materials) -> MO (make product) -> PO (send to vendor for finishing) -> Receive to inventory -> Ship
