One-off events: These are special events that affect the demand for a product, such as promotions, holidays, or product launches. You can use the one-off events function in SAP S/4HANA to create and maintain events and assign them to products. The system considers the events when generating the forecast and adjusts the demand accordingly.
Past sales order quantities: These are the historical data of the actual sales orders for a product. You can use the past sales order quantities as the basis for forecasting the future demand. The system applies statistical methods and algorithms to analyze the past sales order quantities and identify the trends, patterns, and seasonality of the demand.
Market intelligence: This is the external information that influences the demand for a product, such as market research, competitor analysis, or customer feedback. You can use the market intelligence function in SAP S/4HANA to import and integrate market data from various sources into the forecast. The system adjusts the demand based on the market intelligence data and the weighting factors that you define.
