Hi;

In the Enterprise module of Odoo 15 account.journal, when assigning a journal I get an error that account.journal does not have the _is_payment_method_available attribute.

def _default_inbound_payment_methods(self):
res = super()._default_inbound_payment_methods()
if self._is_payment_method_available('batch_payment'):
res |= self.env.ref ('account_batch_payment.account_payment_method_batch_deposit')
return res

Exception

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/odoo/odoo-server/odoo/http.py", line 644, in _handle_exception
    return super(JsonRequest, self)._handle_exception(exception)

    raise exception.with_traceback(None) from new_cause
AttributeError: 'account.journal' object has no attribute '_is_payment_method_available'

Reviewing I have seen that this method is not defined anywhere. The question is; Does anyone have it defined or has encountered this problem before?

Thank you anyway
