Currently D365FO doesn't support to have multiple language for Legal entity name and this name is printed on sales invoices, purchase orders etc.
It is possible to print sales invoice and purchase order in customer/vendor language. However, legal entity name doesn't translate.
We would like to have function to support multiple language for Legal entity name.

Below scenario is very common practice for Japanese companies which have a business with foreign companies.
Normally, Japanese customer setup their legal entity name in Japanese.
When they sell items to foreign customers, they need to print sales invoice in English.
In this case, they need to print their company name in English instead of Japanese.
