You use the Delta Drill chart to drill through a delta by assigning an order to each of the elements that determine the delta. When you select a dimension, two items to be compared are extracted. Delta Drill charts can have more than one drill dimension.
In addition, you can also use another Delta Drill environment to view the absolute values of each of the items.
Delta Drill charts are particularly useful in scenarios where you want to view the delta across two dimensions - Budget Vs Actual, for example, and the composition contributing to the delta.
