5.2 Calendar Mechanisms
5.2.3 Calendars
any time you specified WEEK-DAY as the criteria, the schedule or job will be
selected. The rest of the lines pertain to the datetable. They include the
workday, the workday of the week, the workday of the month, the workday of
the year, the work week, the relative days of the month, and the various
accounting days.
After reviewing this report carefully, you should understand how the criteria
vocabulary works with the Gregorian calendar and datetables.
To use calendar processing, set aside everything you have learned so far about
the Gregorian calendar and datetables. Calendars use an entirely different
approach to selecting schedules and jobs. Do not try to relate any discussion of
calendars to the other calendar mechanisms.
We do not recommend that you use calendars. Instead, try to do all of your
definitions with datetables or the Gregorian calendar or a combination of the
two. Consequently, the description of calendars will be brief. If you do not
intend to use calendars, you can skip this subtopic.
You would use this mechanism if a set of schedules have to run on specific
dates during the year and there is no relationship between the dates. Then you
would use a calendar to define just the days of the year on which those
schedules run.
When using calendars, a schedule or job is selected on the days that the
calendar specifies as workdays. With calendars, the criteria language is not
used for selection, only for defining predecessors. Again, the only thing you
specify on a schedule for selection purposes is the calendar name. The same
calendar also applies to the jobs in that schedule.
The following steps describe how to use calendars.
5.2.3.1 Step 1: Define the prototype calendar
Before you define any calendars, first define a prototype calendar. This
calendar defines your holidays and what to do if jobs are selected on holidays.
In case of holidays, should jobs run on the prior workday, the next workday,
or not at all? The prototype calendar must have a name PROTOyy, where yy
is the year (for example, PROTO87).
You can only have one prototype calendar for each year which means that
there is only one set of holiday definitions. Once the prototype is defined, you
can define calendars specific to your needs. Defining a prototype calendar
follows.
