Crystal Reports for Eclipse Designer Guide

Characteristics of the data needed for hierarchical grouping

You can group data in a report to show hierarchical relationships. When you group data hierarchically, Crystal Reports sorts information based on the relationship between two fields.
A hierarchical relationship must be inherent in the data that you use for the report:

Note: Mina has no corresponding Supervisor. This data implies that Mina is a top-level supervisor who does not report to anyone else in this table.
In the report, the hierarchical groupings may be represented various ways. For example:
