Field help (STTPER) 

This entered number corresponds to a number of calendar days.
It is used for various purposes:

  • the calculation of the default date of the cumulation period start for the statistical data calculation.
    When starting the calculation of the ideal classes, the system deduces this number of days from the current date in order to obtain the start date of the calcuation period that is displayed by default on the launch screen.
  • the calculation of the default date of the cumulation period end for the statistical data calculation.
    When starting the calculation of the ideal classes, the system deduces this number of days from the current date in order to obtain the end date of the calcuation period that is displayed by default on the launch screen.

During the calculation of the ideal classes, the system deduces the days not worked from the defined calculation period. The days not worked are determined from the calendar for the forecast period and from the movements for the historical record.
