The DrillDown feature enables you to use a predefined drill-down path to go directly to the next item in a hierarchy when working with dimensional analysis. For example, you may need to find out if a particular product sells better in different regions of the country. Using a drill-down path, all you have to do is follow the drilldown path to discover which state or even city is a more appropriate market for your product.
To drill down into a Pivot or Chart label:
Select any label for drill-down analysis.
Because the drill-down into feature is not context sensitive, access the drill-down from any label shown.
Click Drilldown into on the shortcut menu.
All available drill-down paths are displayed. Each drill-down path shows the topic which is being drilled into, and the label from which it was drilled.
After you specify the drill down label, the label is added to the data layout and breaks out the additional data according to the label selected for drill-down.
