Function documentationTime Series

 

You can use different types of time series to provide the system with historical demand data (transaction data).

Integration

The Demand Data Foundation (DDF) module in SAP Customer Activity Repository can receive the time series from an external SAP or non-SAP application. For more information, see Integration Information and Inbound Processing.

The Unified Demand Forecast (UDF) module in SAP Customer Activity Repository can use the provided time series and master data as input for demand modeling and forecasting. For more information, see Unified Demand Forecast and Outbound Time Series.

Prerequisites

  • Make sure that the prerequisites under Data Management have been fulfilled.

  • Make sure that your historical data is at daily granularity. Weekly data is currently not supported. For more information, see Customizing (transaction SPRO) under Start of the navigation path Cross-Application Components Next navigation step Demand Data Foundation Next navigation step Imported Data Next navigation step Time Series Next navigation step Define Time Series for Key Figure Configuration End of the navigation path.

Recommendation Recommendation

Time series length: We recommend that you provide 2 years of historical demand data to ensure the proper interpretation of seasonality, trend, and other yearly demand influencing factors (DIFs).

Sanity check: A data validation report is available that you can run prior to modeling and forecasting. It allows you to identify potential issues in the provided input data and rectify them as needed. When you run the report, the system executes modeling and forecasting in simulation mode on the input data and indicates any issues found. For more information, see SAP Note 2161484Information published on SAP site.
