The CPM Procedure

Input Data Sets and Related Variables

The CPM procedure uses activity, resource, and holiday data from several different data sets with key variable names being used to identify the appropriate information. Table 4.9 lists all of the variables associated with each input data set and their interpretation by the CPM procedure. The variables are grouped according to the statement that they are identified in. Some variables use default names and are not required to be identified in any statement.
