Defining the reporting period

You can control the length of the reporting period with:

1. Control statements (DATE, RTOD, ETOD, and STOD) that indicate a specific range of dates and specific ranges of times.
2. The SMF record data set. The control statement defaults for the reporting period include all dates and all times in the SMF record data set. If you omit control statements, the Postprocessor generates reports for all dates and times included in the SMF record data set.
