what do drill down m
Drill Down and Drill Through. Drill down and drill through make reporting powerful and useful. Drill down and drill through are two extremely powerful features in business intelligence. They both give the user the ability to see data and information in more detailâalthough they do so in different fashions. Drill down is a capability that takes the user from a more general view of the data to a more specific one at the click of a mouse. For example, a report that shows sales revenue by state can allow the user to select a state, click on it and see sales revenue by county or city within that state.
