Stock Picking Product Assortment

This module links product assortments (already configured on contacts) to warehouse transfers. When you open a transfer and choose a contact in the Contact field, Odoo looks at the assortments applied to that contact and to its parent company, combines their rules, and works out the list of allowed products.

• On the transfer form, the Product column of the Operations list is filtered: only products belonging to the partner's assortment can be selected. Products outside the assortment are not offered.
• The same restriction applies on the detailed operations screen used to register the individual move lines, so the filtering stays consistent when you record quantities.
• If the partner has no assortment, nothing changes: all products remain available as usual.

The module adds two technical fields on stock.picking (the list of assortment products and a flag telling whether an assortment applies). These are hidden on the form and are only used to drive the filtering. No new menus, buttons, reports or scheduled actions are added. The behaviour is purely a restriction on product selection, based on the partner set on the transfer.
