I have had cases where the AdvanceReport preview window:
Doesn't show pie charts
Doesn't show all boarders of an attribute
Attribute doesn't wrap correctly
As you can't also print from the AdvanceReport preview window, I format for PDF output, where in my case, the above items show correctly.
In my case of the boarders not showing on some sections of the report, I attempted the zoom %, no differences. Saved as PDF, boarders showed correctly.
CA PPM V15.3 re-introduces running JasperSoft in pre-v15 'Reports' facilities, which this then generates the JasperSoft report with output PDF/PPTX/XLSX - potentially in the future, 'Advance Reports' may restricted to 'administrators' and general users use the 'Reports'.
