To create a transaction at account voucher, I created a new cursor and if my case is correct, then i used new_cr.commit() else new_cr.rollback()
Is it possible to have rollback() failure? or if possible? How does odoo 7 check rollback failure.
Odoo is the world's easiest all-in-one management software.
It includes hundreds of business apps:
- CRM
- e-Commerce
- Accounting
- Inventory
- PoS
- Project management
- MRP

I believe there is still a chance that there might be a failure within rollback, although I would belive it would be quite rare (sudden network interuption, corruption in the shared memory, etc.). However, OpenERP seems to leave it to psycopg to handle the error (odoo/odoo/openerp/sql_db.py).
