Functions in Forecasting (Enhanced)

Use

As of SAP SCM 6.0, new functions will exist for forecasting in the following areas:

  • Forecasting strategies
  • Forecasting profiles
  • Outlier correction
  • Forecast errors
  • Automatic model selection
  • Forecast approval

Forecasting Strategies

Up to now, it was only possible to use the forecasting strategies delivered by us for forecast creation. As of SAP SCM 6.0, you can create your own forecasting strategy in the Business Add-In (BAdI) BAdI: Define Customer-Defined Forecast Strategy (/SAPAPO/BADI_FCST_STRATEGY) and select it in the forecast profile.

Forecasting profiles

Previously you could only pass on forecasting profiles along a specific hierarchy. As of SAP SCM 5.1, you can, for example, also copy a forecasting profile that you created for a product or location product to another location product. To copy a forecasting profile, you can either use the planning service manager or you can manually copy the forecasting profile (or even just particular parameters from it) in the Forecast Profile screen.

Outlier correction

Up to now, it was only possible to use the outlier correction delivered by us. As of SAP SCM 6.0, you can create your own outlier correction in the BAdI BAdI: Define Customer-Defined Outlier Correction (/SAPAPO/BADI_OUTLIER_CTRL) and select it in the forecast profile .

We deliver the BAdI BAdI: Define Customer-Defined Outlier Correction with an example implementation based on medians and inter-quartile ranges, and especially suited to slow-moving location products.

Forecast errors

Up to now, it was only possible to use the Root Mean Square Error (RMSE) forecast error in automatic model selection. As of SAP SCM 6.0, you can also work with the following forecast errors:

  • mean percent error (MPE)
  • mean absolute percent error (MAPE)
  • mean square error (MSE)

You can select the desired forecast error in the forecast profile.

In the BAdI BAdI: Define Customer-Defined Forecast Errors (/SAPAPO/BADI_FCST_ERROR), you can define your own forecast error and select it in the forecast profile.

We deliver the BAdI BAdI: Define Customer-Defined Forecast Errors with an example implementation. We have defined the mean absolute error (MAE) forecast error in this example implementation.

Automatic model selection

Previously you could only define one configuration for automatic model selection. As of SAP SCM 5.1, you can define profiles for automatic model selection and assign these on location product level in the forecast profile.

To be able to use automatic model selection in SAP SCM 5.1, you must implement SAP Note 102945.

Forecast Approval

Up to now it was only possible to use the forecast approval with the logic delivered by us. As of SAP SCM 6.0 you can also create a final forecast determination profile, in which you define which forecast key figures(s) you want the system to adopt for the final forecast. In addition you can create a customer-defined forecast approval logic in the BAdI BADI: Define Forecast Approval Logic (/SAPAPO/FCST_APPR_CUST_DEF).

In the forecast profile you can either specify which of the final forecast determination profiles the system should use, or whether the system should use the logic implemented by you in the BAdI.
