    for record in self:
        acc_res = acc_lines.search(['statement_ids'])
        record.journal_id = acc_journals.search(['acc_res.journal_id.id'])

In odoo generally only one accounting entry gets created for each session at the time of closing.

So if you want to show up the debit and credit amount of those orders of then you have to first change the code and create order wise accounting entries.

So either change the way how it works or should change the requirements to any alternate solution.
