Original Language 

You have the option of defining an original language (independently of the current logon language) for language-dependent text entries. If a translation process is connected to the Integration Builder, this ensures that the text is assigned to the correct language. You can set the original language for the object and the object documentation separately.

You set the original language in your personal settings.
