I'll guess that you didn't mean "certain subreport in a specific group only on last page". If it's a specific group, then it will probably have to ALSO be the last group since it's on the last page, right? Perhaps you meant can I show a subreport at the end of the report.
And "Can the same things be done" to what footer, the page footer, report footer, group footer? Please state specifics, it doesn't take that much time to do it right the first time and it saves everyone time.
Place the report in the report footer, it will print at the end.
If you meant to say that you need it at the end of each group footer, then right click the groupfooter, select insert section below, right click the new section (GF B) and select format section (may differ, software dependent), X 2 next to suppress and place soemthing like:
{table.groupfield} = next({table.groupfield})
or
onlastrecord
You can then place another one in the report footer if you need some other sort of summary...
This should help, if not, please post technical information.
