def compute_overheads(self):
    if self.total_cost != 0:
        print(self.total_cost)
        debit_value = {
            'name': 'Production Overheads',
            'debit': self.total_cost,
            'credit': 0.0,
            'account_id': self.credit_account,
        }

        credit_value = {
            'name': 'Production Overheads',
            'debit': 0.0,
            'credit': self.total_cost,
            'account_id': self.credit_account,
        }

        values = {
            # 'journal_id': self.
            # 'date': self.date.today(),
            'ref': 'Production Overheads Costs',
            'state': 'draft',
            'line_ids': [(0, 0, debit_value), (0, 
        }
        move = self.env['account.move'].create(values)
        return move
