Use

You can use the Alert Monitor to monitor forecast alerts for Structure linkDemand Planning (DP). In a forecast alert profile, you make a user-specific selection of alerts that are relevant for your area of responsibility, for example, your planning book.

Prerequisites

·         Optional: You have specified priorities for forecast alerts in Customizing. If you do not specify priorities, the system issues all forecast alerts as warning messages, as standard.

·         In the Structure linkForecast Profile for Demand Planning, you have defined a diagnosis group. You maintain separate diagnosis groups for Univariate forecasts and MLR (multiple linear regression). The diagnosis group contains the threshold values, which trigger an alert when they are exceeded. For Univariate forecasts these are always maximum values. For MLR the values can be either upper or lower limits, depending on what kind of adjustments you are dealing with.

Note

§         MLR adjustment measures are calculated for the entire model. Exceptions are Durbin-H, the T-test, and the mean elasticity, which are calculated separately for each variable. (The mean elasticity is not included in the diagnosis group. However, you can display it in interactive planning).

§         You can also define diagnosis groups in the forecast view and MLR view within interactive planning.

§         You can only enter threshold values for the diagnosis groups. You cannot change them in the alert profile.

Features

We can divide forecast alerts into two groups of alert types:

·        Alerts for Univariate forecasts

In Demand Planning, you can measure the accuracy of the forecast using various calculation methods for forecast errors. The system saves several forecasts for a specific period, and compares these forecasts with the actual values. If a variance occurs, the system generates an alert. For more information on calculating forecast errors, see

¡        Structure linkMean Absolute Deviation (MAD)

¡        Structure linkError Total (ET)

¡        Structure linkMean Absolute Percent Error (MAPE)

¡        Structure linkMean Percent Error (MPE)

¡        Structure linkMean Square Error (MSE)

¡        Structure linkRoot of the Mean Square Error (RMSE)

·         MLR alerts

You use MLR to evaluate the effects of various causal factors on the forecast. There are various functions available for this purpose. The system generates an alert if the calculation result from the statistics falls short of, or exceeds, the upper or lower limits. For more information on the statistics, see

¡        Structure linkR Square

¡        Structure linkAdjusted R-Square

¡        Structure linkDurbin-h

¡        Structure linkDurbin-Watson

¡        Structure linkT-test

Activities

...

       1.      Select the alert types that are relevant for you.

       2.      Select the planning book for which the system should determine alerts. You can enter a selection restriction.

A planning area characteristic defines a partial quantity of all the data contained in the planning area. If you enter a selection range for a specific characteristic, only those alerts will be displayed that have that particular characteristic. If you do not enter a selection, the system determines alerts for all selections in a planning book.

Example

The planning area contains forecasts for all locations and products for a region. When you select a location or a product from the planning area, the system only generates alerts for this location or product.

       3.      Specify the text and the message that will be displayed in the Alert Monitor MiniApp.

       4.      If necessary, assign the forecast alert profile to your Overall Alert Profile, your Structure linkSCC User Profile, or your user in the area menu for Demand Planning under Environment ® Current Settings ® Assign Planner to Alert Profiles.

Recommendation

For performance reasons, we recommend restricting the alerts to be displayed to a minimum.
