What is an external document in oracle applications?

External documents are business documents corresponding to customers,trading partners (ie.external person).
That could be invoices,bills of landing,package slips.
Oracle E-Business Suite Release 12 is capable of producing external documents in any of the active languages,simultaneously and with a single request. ie. Customers can get the documents in the language they are comfortable with.
A company’s customer in France, for example,could receive invoices printed in French, and a customer in India could receive invoices printed in Hindi.
We can send external documents to different printers based on language, and route completion notifications to different people according to the requested language.
For example, we could route all French documents to one printer, and all other documents to another printer. We could send completion notifications for Spanish documents to one user, and all notifications, including Spanish, to another.
