Normally, master/detail report are implemented using nested SQL statements. All ReportEditor demos work in this way.

But this is not the only possible solution.
For example, a master/detail relationship may be created using properties of datasets (see "4 - Master-detail predefined" demos for FireDAC or IBX). You can implement your report in a similar way, using OnProcessRecord event. This event occurs before processing each record. When a new record of the master table is processed, you can apply a filter to the detail table.
