Demand Planning

You can use demand planning to plan future demand for specific customers, regions, or sales organizations. Demand planning allows you to forecast future demands and you can create both quantity-based and value-based plans.

You define the planning level using characteristics in the system. All the planning data in demand planning is stored in the form of key figures and it contains a numerical value.

Using time characteristics, you can view, plan, and store the data. Historical data is imported to SAP NetWeaver BW system of SCM with the use of BW extractors.

Various mathematical methods can be used to analyze historical data for demand planning.

  • Moving average
  • Constant model
  • Trend model
  • Seasonal model
  • Exponential smoothing

In analyzing historical data, you can use various constant models for products with historical data that changes little over time.

In Demand Planning, seasonal models are used for seasonal products. As per requirement, there can be different seasonal products - candles, ice creams, etc.
