Field help (DES) 

This field is used to link a description to its record. This description can be printed on the records, displayed when the record code is entered in a screen, or used on selection.
The title, used by default in the reports and entry masks is replaced by the short title when it is required by display and print constraints.

By default the short title, the long title or the column header of a data are recorded (on creation/update) in the connection language of the user.
You can add your translation in another language using the Translation function:

A user who logs on with this language will view the short description, long description or column header in their connection language if a translation exists. Otherwise, these descriptions will be available in the folder language.

SEEINFOThe connection language must be defined as a default language for thefolder.
