You can have up to 500 sheets of each type (including data tables) in a single Prism project. Each data table can contain:

•Any number of rows (limited by RAM and hard disk space). We've tested hundreds of thousands of rows.

•Up to 1024 data set columns. Prism 8 only allowed 256. Prism 5 only allowed 104.

•Up to 512 subcolumns. Prism 8 only allowed 256. Prism 5 only allowed 52.
