About the CurrentCulture System Function
The CurrentCulture System Function contains a User's culture and can be used in Expressions, One-Step Actions, etc. to handle different languages and to return a string representation of the culture for the current thread.
The CurrentCulture System Function can be used with or without globalization features.
For example, CurrentCulture can be used to create e-mail templates in different languages. If CurrentCulture is set to de-DE, then clicking a button or running a One-Step will initiate the German e-mail template. If CurrentCulture is set to pt-BR, then clicking the same button or running the same One-Step will initiate the Portuguese e-mail template.
Each Business Object contains a Created Culture Field. When a new instance of a Business Object is created, the Field is auto-populated using the CurrentCulture System Function.
