Issuing Documents in the Customer's Language 
If your company has customers in foreign countries, you may want to issue invoices or other documents in the customer’s language. For this purpose, you need to translate your company’s specific field values, such as product names and product descriptions. Standard document texts, such as field labels, are provided automatically, based on the language settings in the master data of the customer as well as the layout settings.
Example
An invoice item for a U.S. and a German customer looks like this:
Item: Supertasty Chocolate Bar |
Description: low fat |
Artikel: Superlecker Schokoriegel |
Beschreibung: fettarm |
The translations for the standard texts Item and Description are automatically inserted, based on the master data of the customer and the layout settings. For the field values Supertasty Chocolate Bar and low fat, you have specified translations.
