Hello Community.

In the model account_move, I have a field called "invoice_origin" that have the ID of a sale order. It's define like this:

invoice_origin = fields.Char(string='Origin', readonly=True, tracking=True)

I need the entire sale.order because a need the the "business_unit_it", but I onlyhave this data. How can I search and return the entire sale.order, in the move_account file?

I've tried something like this but it doesn't work

client_order_ref = fields.Char('get_sale_order().client_order_ref')

# Get a sale order with the invoice_origin field
def get_sale_order(self):
    sale_order = self.env['sale.order'].search([
        ('name', '=', self.invoice_origin)
    ])
    return sale_order

Thank you! :)
