Creating an on-demand subreport
On-demand subreports can be especially useful when you want to create a report that contains multiple subreports. In this case, you can choose to have these subreports appear only as hyperlinks.
The actual data is not read from the database until the user drills down on the hyperlink. This way only data for on-demand subreports that are actually viewed will be retrieved from the database. This makes the subreports much more manageable.
Note: Data for an on-demand subreport is not saved unless the subreport is actually open in a preview window.
To create an on-demand subreport
- Place an ordinary subreport in your primary report.
Click the Format button on the Supplementary toolbar.
The Format Editor dialog box appears.
- Click the Subreport tab and select the On-demand subreport check box on.
- Click OK.
