When printing tables you can execute calculations on two ways:
This section, as an example, describes how to sum up different currencies:
You can use these calculations forprinting old tables as well as for the new table nodes (see: Printing Tables).
You usually calculate totals within data loops of the loop or table nodes. Forgrand totals or subtotals of the grand totals at the end of a page use the footer for output. The output control of the footer (see: Processing Loops and Tables) in this case requires a calculation of the total that is in sync with the output.
Forsubtotals by sort criterion use events for summing that are triggered after a break in the sort level.
