Hello fellow colleagues,
I’m facing a situation as follows:
I’m expecting a delivery to land at Hamburg port, there it will be split into two parts: One goes to our own warehouse, a second directly to a customer. So it’s a kind of drop shipment, but not exactly the same.
I tried to manually create a move at inventory&stock, “from supplier” “to customer” and as origin of this move used fitting “purchase line”. But when trying to carry out the move, this error appears:
```auto

Does my approach make sense? - What can I do about it? - Tryton v7.0.

This is exactly a drop shipment.
In Tryton they must be define when creating the purchase that it will be a drop shipment.
You can not create a move from supplier to customer in a supplier shipment.
But as you are talking about split, I’m wondering if indeed you do not have a kind of warehouse in Hamburg. If it is the case you should receive the product in this warehouse and then make an internal shipment to your other warehouse and a customer shipment.

As I do normally not drop ship these products, setup and handling of a drop shipment would be challenging.
But the idea of a distinguished warehouse at Hamburg port works perfectly for me. It does the moves and creates the invoice for my customer.
Thank you a lot, Sir.
