I have a customer who requests to have on the invoice the number of shipments linked as extra references.
It is pretty easy to do by just extending
get_origins to append the shipment names of the moves linked to the invoice lines.
So I'm wondering if it should be a standard behavior? For me, the shipment number is redundant with the sale reference because they appears on both document invoice and delivery order. But maybe there are some countries with specific rules about that?
