reports are the standard reports that are accessed through a hyperlink on a text box in the original report. Drill through is a term used to describe the act of exploring or browsing items like folders, files or related components.
reports initially hide complexity and enable the user to toggle conditionally hidden report items to control how much detail data the user wants to see. Drill down reports must retrieve all of the possibl data that can be shown in the report. I recommend that you use drillthrough report if your report has a large amount of data.
