Evaluation of symbolic dates
You can use
symbolic dates
for values of
Date
and
DateTime
properties in reports. Some symbolic dates identify a single day, such as
Yesterday
or
Tomorrow
. Other symbolic dates define a period (an inclusive range of dates), such as
Current Month
or
Previous Quarter
.
When evaluated, a symbolic date can produce a single day or a pair of days, depending on the operation in the Condition field.
-
When the condition is
IS EQUAL TO,
the evaluation returns both the starting day and ending day, defining an interval. (For the symbolsYesterday
,Today
, andTomorrow
, the range is 1 day long.) -
When the condition is
IS GREATER THAN
orIS GREATER THAN OR EQUAL TO
, the evaluation returns the starting date. -
When the condition is
IS LESS THAN
orIS LESS THAN OR EQUAL TO
, the evaluation returns the ending date.
All dates are computed relative to the current day in the time zone of the user, and not
the time zone of the server. So, a user in London, who is working just after midnight, may
find that the symbolic date
Today
is January 1, 2010, but at the same
moment, on the same server, a user in California finds that
Today
evaluates
to December 31, 2009. These results are irrespective of whether the server is located in
California, England, or in any other time zone.
Example
In this example, you want to include in a report only operators who signed on during the current month. When running the report on October 16, you can enter October 1 as a starting date and October 31 as an ending date. But if you want to run the report again in November, you have to enter November 1 and November 30.
Instead of manually entering the starting date and ending date each time you run the
report, you can use the symbolic date
Current Month
and run the report at
any time.
For a detailed example, see the Pega Community article How to use symbolic dates in report selection criteria.
