Schedule Data Set
There is now yet another difference between the forms of the Schedule
output data sets produced by the PM and CPM procedures. The Schedule
output data set produced by the PM procedure creates a new set of
observations when there are resource-driven durations.
The PM procedure contains three sets of observations, identified by three
different values of a new variable, OBS_TYPE:
- The first set of observations contains one observation for every activity
in the project. The value of the OBS_TYPE variable for these observations
is `SCHEDULE'. These observations contain all the activity information such
as the duration, the start and finish times, the resource requirements,
and so forth.
-
The second set of observations contains one observation for every precedence
constraint in the project. The value of the OBS_TYPE variable for these
observations is `LOGIC'. These observations contain all the precedence
information such as the activity, successor, and lag information.
-
The third set of observations is present only if the project has
resource-driven durations. The value of the OBS_TYPE variable for these
observations is `WORK'. These observations specify the WORK value for each
resource used by each activity in the project.
