About the default user locale preference
The Marketing Platform contains a default locale attribute that applies to all IBM® Unica Marketing applications that implement it. You can set this default by setting the value of the Region setting property in the Suite category.
For details on this property, see its online help in the Configuration area or the Marketing Platform Administrator's Guide. To learn whether an IBM® Unica Marketing application implements this attribute, see the documentation for that application.
In addition, you can override these default values on a per-user basis by changing the value of this property in the user’s account. See Setting the per-user locale preference for details.
