Changing Extended Settings of the Central Performance HistoryLocate this document in the navigation structure


Use the extended settings of the CPH to set the repetition periods of the data collection and reorganization jobs to suit your needs. These jobs read the desired performance values from the monitoring segment, store them in the CPH, and reorganize the contents of the CPH. For more information about these jobs, seeCollecting and Reorganizing Performance Values.

Reduce the period of the jobs to increase data security in the case of an outage or a delayed execution of the job, and increase the period to reduce the workload caused by the job.


The default values for the periods of the data collection jobs have been set so that no data is lost even if one execution fails. The numerical values of the periods are also not whole number multiples of each other, to try to avoid the jobs starting at the same time, as far as possible.

You can also define which output formats are available to you when creating report definitions (seeCreating a Report Definition). An output data format defines the resolution and the aggregate of the reports that are based on the relevant report definition (such as monthly aggregates in an hourly resolution; for an explanation, see Aggregation).

By default, it is not possible to include output formats that are infrequently used (such as yearly aggregates) in the report definition; however, if you require this output format, activate the parameter MORE_REPORT_OPTIONS.

  1. Start the administration transaction of the CPH by calling transaction RZ23N.
  2. To change the extended settings, choose Extended → Extended CPH Settings.
  3. The Change CPH Parameters screen appears. To change one of the specified parameter values in the table, and choose the relevant line by double/clicking it. Enter the desired value and confirm your entry and leave the screen by choosing Back ().

    If you have changed one of the values, but this change has not yet been saved, an X is displayed in the Changed column for the relevant line.

  4. To reset one of the values to its default value, select the relevant line, and choose the button Reset Value to Default ( ).
  5. Save your changes.
