Hello, How to cancel or void journal entry in odoo 10 CE? I just want to leave the journal entry as it is. If i mistakenly created JE, i will just unpost it. The unposted JE are in editable condition... I want to restrict that
You would need to do little customization for that. You can create a new state in Journal Entry (account.move).
Now, override the method button_cancel and call the super and after that set the new state instead of draft.
res = super(...).button_cancel()
