How many types of subreport are there?


There are three types of subreports
a.Unlinked Subreport
ie the subreport doesn't depend on the main report
at all.

b.Linked subreport

A linked subreport is handy when we need to display
related data elements from more than one database table on
a report

c.On-Demand Subreport

If your report has a section that handles a large number of
records, you can put that section into an on-demand
subreport. An on-demand subreport appears as a hyperlink in
the primary report. When you open the primary report, no
data is retrieved for the on-demand subreport until you
drill down on the hyperlink.
