Open functionality is currently configured only in the Site application and only for opening URIs.
In Site, from a URI table, you can right-click a URI to display a web page in a web browser. To view a URI in its native format (such as HTML), Data Workbench must have access to the referenced location and the application needed to open that item. For example, to view a web page, Data Workbench must have access to the Internet as well as have a web browser installed.
Right-click an element of the dimension and click Open URI.
The URI opens in its native application.
