Sale Dropshipping

Makes it better to deal with purchases with known sale schemes, specially the following case: 1) normal 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.
