Returns the group level to which the report has been drilled down to - 0 if no drill-down has been performed, otherwise the 1-based index of the group the report has been drilled down to.

This can be useful for example to suppress elements if the view is currently at a certain level or higher (e.g. as "suppress" property formula).
