When you place an unrelated nested report in a base report, the entire nested report appears with each row of the base report.
To place an unrelated nested report in another report:
Create or open the report you want as the base report.
Select Insert>Control>Report from the menu bar.
In the Design view, click where you want to place the report.
The Select Report dialog box displays, listing defined reports (DataWindow objects) in the current target’s library search path.
Select the report you want to nest in the base report, and click OK.
A box representing the nested report displays in the Design view.
Select File>Save from the menu bar and if the base report is newly created, assign a name to it.
