Add cumulative totals to break totals by dimension and restart them at each dimensional grouping in a pivot table. Cumes work best when all dimensions are located at the column or side of the pivot table, and data label column heads are placed orthogonally.
The Pivot Cume dialog box is displayed.
Select the scope of the pivot cume from the drop-down list box.
The Scope drop-down list box includes all of the dimensions in the pivot table. The default scope is the lowest level dimension that is displayed in the pivot table.
A new fact column is added that maintains a cumulative running total of the original fact by the dimension (scope) specified.
