If you are unfamiliar with Financial Management, see the Financial Management documentation, available on the EPM Documentation Library. To open this library, from the Smart View ribbon, click the arrow next to Help, and then EPM Documentation.
In Financial Management, if you use the @CUR functionality in a data form, when the form is imported into Smart View, the @CUR member is taken from the background POV for the selected application.
The Active Member option is available only if the application has been set up for Organization by Period. For information on Organization by Period, see the Financial Management documentation.
