14.3.1 Update to the Forecast File

You can use the Save forecast option on the Workload
Forecasting Analysis control screen shown below to
save predicted values of the Analysis variable in the
Capacity Planner Forecast file.

In the Forecast file, future values are stored in a special
way that is used by other functions of the CA MICS
Capacity Planner to produce comparative graphs and charts.
The FILE_NO variable is used to distinguish between the
various types of observations within Forecast files. The
Workload Forecasting Analysis, Multivariate Regression,
Univariate Model Forecasting, and Business Element
Forecasting facilities store a future value with a FILE_NO of
11, and a confidence range with a FILE_NO value of 12. In
addition, each observation of a forecast contains the
variables FORYEAR and FORMNDY, FORWEEK or FORMONTH, which
contain the dates for the most recent historical data used in
making the forecast.  These concepts are discussed in more
detail in Section 3.2.
