User Default Currency
This is the currency shown by default when you define new cost transactions. This currency is also used when field values require currency to be displayed in the User Default Currency. Archibus applications include the User Default Currency only if you have enabled the Archibus Enhanced Global Feature Set.
The User Default Currency is determined from the locale selected in your user profile in Web Central (that is, from the Archibus Users table), or the preferences in Smart Client; the scope is per-user.
