The above server error caused the following client error:
RPC_ERROR: Odoo Server Error

How you take this external id: bsd.posting.record_id ?

To get external id: https://www.youtube.com/watch?v=B4EbqacpWD0

module_name.xml_id means like this bsd_payroll.bsd_payroll.xml_id ?

Yes. module_name is the name of your module and xml_id is the view/action id. In your case, it should be bsd_payroll.bsd_payroll.

I'm still confused, can you give a more detailed example
here is my code:
class BSDPosting(models.Model):
_name = 'bsd.posting'
_description = 'BSD Posting'

nama = fields.Char(string='Nama Transaksi', required=True)
date_from = fields.Date(string='Date From', required=True)
date_to = fields.Date(string='Date To', required=True)
posting_date = fields.Datetime(required=True, string='Waktu Mulai')

def action_schedule_posting(self):
# Menjadwalkan proses posting untuk besok menggunakan mekanisme cron Odoo
posting_date = self.posting_date
code_model = "env['bsd_payroll.bsd_payroll'].action_posting_gaji()"
self.env['ir.cron'].sudo().create({
'name': 'Posting Take Home Pay',
'model_id': self.env.ref('bsd.posting.xml_id').id,
'state': 'code',
'code': code_model,
'nextcall': posting_date,
'interval_type': 'days',
'numbercall': 1, # Hanya sekali
'active': True,
})
and here is my view:
