5.2 Calendar Mechanisms
5.2 Calendar Mechanisms
Most of the examples presented so far have used explicit vocabulary such as
MON for Monday or WEEK-DAY for Monday through Friday, but this
oversimplifies what happens in real life. For example, we do have holidays.
Your accounting month may not begin on the first of every month. Some
months have four weeks, while others have five. There can be quite a variation
not only between different companies, but even different divisions within a
company.
Unicenter CA-Scheduler addresses all variations using three different calendar
mechanisms:
The Absolute Gregorian Calendar
Defines specific keywords that have absolute dates associated
with them. For example, the DAILY keyword causes a job to
be selected every day including weekends and holidays;
WEEK-DAY causes selection on Monday through Friday
including holidays; and so forth. This mechanism is
determined by the system and you do not have to define
anything; just use the keywords.
Datetables
Calendars
Define workdays, holidays, accounting days, and accounting
periods. This is the most flexible calendar mechanism and is
the one recommended. It also provides the easiest transition at
year end. Each schedule defines which datetable to use for
evaluating when to select that schedule and its associated jobs.
Define daily, weekly, and monthly calendars for selecting
schedules and jobs. When using calendars, only the calendar
name determines selection. For example, you cannot also
select based on another job being selected. To use this
mechanism, you must define individual calendars. This is the
mechanism to use if all else fails.
5.2.1 Gregorian Calendar
The Gregorian calendar mechanism is the simplest to understand and can be
used immediately. You do not have to define a calendar or datetable first. All
you do is use the reserved words (keywords) when defining your selection
criteria. Most of the preceding examples used keywords from the Gregorian
calendar mechanism.
This mechanism's reserved words that control selection are based on the
standard Gregorian calendar, not workdays or accounting days. Some
examples of these keywords follow:
