Example 4.9 CALEDATA and WORKDATA Data Sets
This example shows how you can schedule the job over a nonstandard day and a nonstandard week. In the first part of the example, the calendar followed is a six-day week with an eight-and-a-half hour workday starting at 7 a.m. The project data are the same as were used in Example 4.8, but some of the durations have been changed to include some fractional values. Output 4.9.1 shows the project data set.

The same Holiday data set is used. To indicate that work is to be done on all days of the week except Sunday, use INTERVAL=DTDAY and define a Calendar data set with a single variable _SUN_, and a single observation identifying Sunday as a holiday. The DATA step creating CALENDAR and the invocation of PROC CPM is shown in the following code. Output 4.9.2 displays the resulting schedule.
/* Set up a 6-day work week, with Sundays off */
data calendar;
_sun_='holiday';
run;
title 'Scheduling on the 6-Day Week';
proc cpm data=widget9 holidata=holidays

Suppose now that you want to schedule work on a five-and-a-half day week (five full working days starting on Monday and half a working day on Saturday). A full work day is from 8 a.m. to 4 p.m. Output 4.9.3 shows the data set WORKDAT, which is used to define the work pattern for a full day (in the shift variable fullday and a half-day (in the shift variable halfday). Output 4.9.4 displays the Calendar data set, CALDAT, which specifies the appropriate work pattern for each day of the week. The schedule produced by invoking the following program is displayed in Output 4.9.5.

Note that, in this case, it was not necessary to specify the DAYLENGTH=, DAYSTART=, or INTERVAL= option in the PROC CPM statement. The default value of INTERVAL=DAY is assumed, and the CALDAT and WORKDAT data sets define the workday and work week completely. The length of a standard working day is also included in the Calendar data set, completing all the necessary specifications.
To visualize the breaks in the work schedule created by these specifications, you can use the following simple data set with a dummy activity 'Schedule Breaks' to produce a Gantt chart, shown in Output 4.9.6. The period illustrated on the chart is from December 19, 2003 to December 27, 2003. The breaks are denoted by *.
/* To visualize the breaks, use following "dummy" data set
to plot a schedule bar showing holidays and breaks */

e_finish='27dec03:23:59:59'dt;
