Hi Pascal Tremblay,

W.r.t your query, I have gone through it and tried to replicate it. Few recommendations which I would like to suggest you based on your query are :-

1) Firstly,Picking in Odoo is basically a “Collection of moves”

2) Now having different Sale Order with different route is possible. This is because while creation/configuration of product we can select/define Routes as per our choice/requirement

3) As you said the two routes have different picking types hence in order to have two different pickings for one single Sales Order(containing several sale order line), every thing depends on the value selected in the field “Shipping Policy”. You can find this by following Sales>Sales>Quotation>Other Information.

4)The significance of “Shipping Policy” is that, if we select “Deliver each product when available” then we can have different pickings based on the availability of the products/Sales order lines.

For Eg. If we two have products P1 and P2,and out of these only one is available at present and the other one is unavailable. Then while checking availability in under Delivery Orders, we can see that one of the Products in the Sale Order lines is unavailable. Now as we have selected the option “Deliver each product when available”, hence we would be able to transfer the available product from the picking to the Partner. Here under STOCK MOVES you would be able to see that partial delivery of product(s)/Sale Order Lines have been done, as two stock moves would be generated for the same Sales Order. For one of the Stock move status would be in “DONE”(Product which is available) and for the unavailable product status would be in “Waiting Availability”(Product which is unavailable)

5) Now to have a different picking for the product which is currently unavailable(i.e. in status “Waiting Availability) we can just click on that particular Stock Move and edit the field Picking Type. Once editing the “Picking Type” and the clicking on Process Entirely the products “Picking Type” would be changed. You can view this by following Warehouse>Traceability>Stock Moves

6) If we select “Deliver all product at once” then all the products/Sales order Lines would be delivered once all products are available. There would not be the option for partial delivery of the products. Here we wont have the option to change picking type as per Sales Order Lines as all product would be delivered at one go.

Hope it helps!

Cheers.
