Definition

Key figure in which the history that has been corrected by the system or manually by the user is stored.

Note

You can correct history (see steps 2 and 3 below) without storing it in this key figure. The corrected history is then displayed in an auxiliary row in the statistical forecast view and cannot be saved. This has no significant performance disadvantages.

If you set the Read corrected history data from planning version indicator, the system uses the corrected history as the basis for the forecast, and not the key figure you entered for historical input in the univariate profile.

Note

Only use this setting if you have corrected the historical data manually. The system automatically takes other effects such as phase-in/out profiles and outlier correction into account. Setting the indicator would then result in such correction being applied each time you execute the forecast. See also note 333565.

Do not use the corrected history key figure if you use either of the functions in the univariate forecast profile that correct history to account for promotions.

The corrected history key figure is made up as follows:

  1. The system takes the original history as the starting point.
  2. If you have entered a value in the Days in period field in the univariate forecast profile, the system adjusts the corrected history key figure based on this average. For a detailed explanation, see the F1 Help of the field.
  3. If you have selected Outlier correction in the univariate forecast profile, the system corrects the historical values that it determines—based on the sigma factor—to be outliers. Historical value markings are also taken into account. See also Structure link Outlier Correction.

Use

You base the forecast on the corrected history key figure if you wish to correct history manually. The prerequisites are:

Note

If you use the history of a "like" product to create the forecast, the system bases the forecast on the original history. It does not read the corrected history of the "like" product. It applies any corrections you have specified (Days in period, Outlier correction, Historical value markings and/or promotion corrections) to the original history.
