I've set up a P&L statement using Crystal 8 that is based on transactional data. Now I am trying to set up a report based on the same data that compares prior period based on the user's selection. I've had some success getting the data displayed using a crosstab report and grouping by current and prior period. The snag is this: there are no sections in which to display running totals or way to set up named groups which I used in the straight P&L. I was wondering if anyone could give me some direction with this. I think I may have to create another table based on the transactional table in order to prepare the data to be grouped this way? Thanks in advance.
