The body of the invoice is divided into category that looks like cross tab:

MODULES
part description......... qty..............price/unit..............total price
.
.
                                             Total Price for Modules: total price
HARDWARE
part description..........qty..............price/unit..............total price
.
.
                                          Total Price for Hardware: total price

The caption "MODULES" and "HARDWARE" will always printed out, just like pre printed form, whether or not there is/there is not data for the the MODULES or HARDWARE.
Data for either MODULES or HARDWARE can be missing, in the case then the body of MODULES empty, only the word "MODULES" printed.

Is this a cross tab? Please help, I could not figure out what kind of grouping if not cross tab.

Thanks!
