I have a crystal report which when generated has a last page that is blank except for the page footer (which indicates the current page, as well as the report title).
This only occurs when the data displayed on the second last page completely fills the page.
Would anyone have any ideas as to why this might be?
In my case, it was an image outside the paper design, i just align it and scaled it to fit my paper.
Instead of using the checkbox on the group footer, use a formula.
The one that I use is
Evaluate if you need a report footer. If don't, be sure supress this section on report.
+1 to Arvo because what he said is probably the case. I'll expand on it a little.
More than likely you have a section that will not totally fit on the second to last page so it spills over to a new page.
Some options you may be able to use are in the section expert are "Keep Together" which keeps all the lines of the section together, either on the current page (if there is room) or on the next (if not), or the "Suppress Blank Section". You could also try to shrink the height of the section, but this will probably not work in all cases.
As Arvo also said, make sure that you do not have the "New Page After" flag set for any of the sections as this could cause it as well.
You have some (almost) empty group footer, which doesn't fit onto last (non-empty) page.
You have to set "New page after" option to some inner group footer section.
