My question includes several point of a domain.
In the basic setting configuration / company / report configuration is defined RML configuration for documents produced by the backoffice (well I think).
It turns out that to produce documents on a V8 Qweb view is used!
In the case of this validation test is used for both front office (website) in backoffice.
Finally this is what I see in my installation.
A rai say I do not understand this architecture if someone could have a clear explanation would be good time for everyone.
