The Translate Part window consists of a heading row used to load a part number. Once you enter a part number, the part name will appear in your company language.
Under Languages you will see flag symbols for the registered languages. Under Translated name there is a row where you enter the translated name, and under that row there are several rows in which you can enter the Translated additional name. You can translate into one or several languages at a time for a part. Just select the language symbol for the language you want to use and translate the names.
