     Posted: 24 May 2010 at 10:33am
Hello.  I have a subreport with a NEW PAGE BEFORE option checked.
 
The problem is, if the sub-report query returns no data, then the page break still occurs and prints a blank page (report and group headers still print, but the detail section is blank).   I need to force a page break when I hit this sub-report, but I don't want the blank page if there is no data in the sub-report.
 
How do I tell Crystal to only perform the page break if the sub-report query has data? 
 
Thanks!

either place a flag in your dataset stating there is no subreport data (stored proc could do this, joining to the tables can't) or run the subreport (or a slightly modified one) to return a count of records via a shared variable and then programmatically enable/disable the pagebreak/display of the 'true' subreport.
