+2) direct delivery (also called drop shipping)
+3) direct invoice
+4) direct delivery and direct invoice
+See the attached diagram in images/purchase_to_sale.png to see the difference between those flows.
+
+In all those specific MTO (by opposition of MTS) cases,
+it will link the sale order line and the purchase order lines together.
+
+A good idea might be to use this module with the mrp_jit module
+if you want MTO flows to be automatically dealt with right
+at the sale order validation.
+
+You can also tell if product suppliers accept drop shipping or not.
+ If they accept it and if sale order
+line has more products than the virtual quantity available,
+then it selects drop shipping by default.
+
+In the out going product list view, you can filter in or out drop shipping picking.
+
+TODO: eventually it might be interesting to do a chained move from supplier to internal location and
+from internal location to customer instead of supplier o customer directly.
+This would enable moves to properly generate accounting moves
+ in the stock journal for better tracking.
