Crystal Reports has many types of
formulas:
The majority of formulas in a report are
report formulas and conditional formatting formulas.
Report formulas
Report formulas are formulas that you
create to stand alone in a report. For example, a formula that calculates the
days between the order date and the shipping date is a report formula.
Selection formulas
Selection formulas specify and limit the
records and groups that appear in a report. You can either enter these formulas
directly or specify the selection using the Record Filter dialog.
Crystal Reports then generates the record selection and
group selection formula. You have the option to manually edit these formulas,
but you must use Crystal syntax. For more information, see
Selecting records.
Running Total condition
formulas
Running Total condition formulas let you
define the condition upon which your running total will be evaluated or reset.
For more information, see
Creating conditional running
totals.
