Drill maps
Drill maps provide users with the capability of viewing data that is not available on the report. It allows analyzing the data within the same or a different context of data on the report. Let's say report 1 is created to view the annual sales of a company, but then the user wants to view the quarterly sales of the company; this can be achieved by drilling.
The user can drill on any object by right-clicking or double-clicking via the developer, or by a single click via the Web, and selecting the direction of the drill. If the user right-clicks on an element, it will drill for that particular element only, whereas if the user selects the header, it will drill for all the elements on that column. If user hierarchies are not defined, then system hierarchies create a default drill map. The drill path includes the destination of the drill, which could be an attribute, a hierarchy, or a template.
