Sale Partner Operating Unit

This module links the customer's Operating Unit to the sales order. When a customer is linked to exactly one Operating Unit and the sales order has no sales team, the order's Operating Unit is taken directly from that customer.

• The Operating Unit on the sales order is computed from the customer's Operating Units (partner_id.operating_unit_ids).
• The automatic fill only happens when the customer has exactly one Operating Unit and the order has no sales team (team_id).
• Orders that already have a sales team are left to the standard logic, so the sales team still decides the Operating Unit in that case.
• The standard sales team computation is also adjusted so it does not override the Operating Unit coming from the customer in these single-Operating-Unit cases.

It touches the sale.order model and works together with the customer Operating Unit and sales Operating Unit modules. Users do not get a new menu or button; the change is automatic when creating or editing a quotation or sales order.
