In the recent SAP Integrated Business Planning 6.1 release, the inventory application has added a new and exciting innovation to provide a systematic approach for the calculation of forecast error. Forecast error is one of the key inputs into safety stock planning. We have introduced a new forecast error calculation operator.


  • Enhancements to calculate and report the historical forecast error, which is input for inventory optimization in the calculation of safety stock
  • Provision of a systematic way to calculate historical forecast error for all combinations of product, location, and customer groups with weekly granularity
  • Features including special handling for intermittent items, forecast bias compensation, and outlier detection
