I have an odd issue with Report Builder 3.0 and a sub report. The report and sub report and based on a date range. If I limit the date range to just a few days (and very few records) my Tablix and my subreport (which also is a Tablix) display just fine. If increase the date range, my sub report disappears. I am fairly new to Report Builder (I have a long history with Crystal Reports), but nothing I have tried so far makes a difference.
