Of course, separate tables can be created for each combination of grouping variable levels. However, all of these details can be exposed at once by pivoting the grouping variables out of the layers and into the row and column of this same table.

Activate the table by double-clicking on it.

From the Viewer menus choose:

Pivot
Pivot Trays

Move the Churn within last month icon from the Layer to the Row tray.

Move the Statistics icon from the Column to the Layer tray.

Move the Geographic indicator icon from the Layer to the Column tray.

Close the Pivoting Trays dialog box.

In the layer of the OLAP Cubes table, select Mean from the list of available statistics.
