Hour 6. Selecting and Grouping Data > Understanding Drill-down Reports

Understanding Drill-down Reports

As we have highlighted, 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 will want 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.

When the term drill-down is used, it implies that a business user has the ability to move from an aggregated or grouped view of the data (for example, sales revenue for each sales district) to a more detailed level of the data (for example, sales revenue for each salesperson in a selected sales district). In Crystal Reports, this is as easy as double-clicking on the involved group data or aggregated graphic.
