I connect Cystal using n/odbc using Native server. I have no problems with performance. Some say it’s slower that Nav reports but if it is then it’s so tiny I don’t notice the difference.
We’re big on creating custom reports here so with crystal we have the capability to create 1000’s if we wanted. not limited by our license. you can sort by anything, columns graphs whaterver you want and the data created can be exported into numerour formats
right to excel or word or pdf or xml or html or csv, you get the idea.
