If you aren't using grouping, try this:
Add an additional section below your last detail section.
In Section Expert, mark the detail section Keep Together.
For the suppress formula for the new section, specify Not OnLastRecord.
Move the content from the report footer to the new detail section.
If you are using grouping, do this in the last group footer instead, and in Group Expert, mark the group Keep Group Together.
