+Allow to propagate a package from a component to a finished product.
+
+This is useful for instance if you want to keep the box of one of the component
+(which could have already a label stuck on it) for your finished product.
+
+Two constraints:
+
+* the component quantity has to be 1 unit
+* the manufacturing order has to produce exactly the BoM quantity
+
+This is to ensure we get only one package reserved for the given component.
