Understanding Drill-down Reports

As you have learned, grouping data facilitates data analysis for business users and enables meaningful summarizations in your reports. Having both the group level and the detail level data available in a view of a report enables the simultaneous analysis of both group level summaries and the supporting detail records (for example, database fields, formulas, and so on). There are situations, however, in which a report consumer or analyst wants to view only aggregated group level information initially and then selectively drill-down into detail records where relevant (that is, drill-down only where the aggregated group level information is interesting, appealing, or stands out). This is easily and quickly accomplished in Crystal Reports through the use of the built-in drill-down capabilities in the product.
