Category
On the Event Message Categories form, define the message categories that will be available to event designers, for example: Order Approval, Expense Report, Time Off Request, System Broadcast, and so on. You can specify the category as metadata that includes a translatable string; for example: FORMAT(sTask).
In that case, the Translated Category field displays the translated string in the currently selected language.
On the Send Message form, specify an existing category when creating a message.
On the Inbox form and the Saved Messages form, specify an existing category to filter messages by that category.
