Hello all,

In the stock.picking model, I want to declare a new field (customer_of_division_id).

If the stock.picking has a value in his sale_id field, I would want to declare the field like this :

customer_of_division_id = fields.Many2one(related="sale_id.customer_of_division_id", 
domain="[('division_of_company_id','=',company_id)]", 
string='Customer of the division')

customer_of_division_id = fields.Many2one(related="partner_id.customer_of_division_id", 
domain="[('division_of_company_id','=',company_id)]", 
string='Customer of the division')

How to achieve this?

Thanks all
