Hi I do not remember anymore how and which fuction enabled this. I remember that there was a possibility to be able to translate the product descriptions.
Can somebody enlighten me ?
Also is there a way to set automatically the proposal, order , invoice and other documents to be issued in the language of the customer
or in English ?
in the settings you need to activate the multilingual interface. If you did you can create all documents in any supported language.
By setting up the standard language per thirdparty the language of the documents will be always in the same as your customer needs it.
