Hi,

I have a field in account.invoice

class AccountInvoiceInherited(models.Model):
    _inherit = 'account.invoice'

     company_selection = fields.Many2one('account.analytic.account', string="Company")

I want to access the value of the field company_selection in another model so i did it using a related field like below.

class AccountMoveInherited(models.Model):
    _inherit = "account.move"

    rel_account_invoice = fields.Many2one('account.invoice', string='Related Account Invoice')
    rel_company_selection = fields.Many2one(related='rel_account_invoice.company_selection')

but when i check the value in rel_company_selection it gives me none i.e., account.analytic.account()

How to access the value of company_selection in account.move model?

Thank you
