 Virtual Data Models for Unified Demand Forecast

 

Virtual data models (VDMs) allow you to access data in one module and use it in another without having to persist the data a second time.

The Unified Demand Forecast (UDF) module in SAP Customer Activity Repository allows you to model and forecast consumer demand. For input, you need to provide historical demand data. The VDMs allow UDF to access views in the SAP HANA content of SAP Customer Activity Repository that provide this input in the form of aggregated historical time series data.

The following VDMs are available:

Note that the consumed time series are not persisted in the Demand Data Foundation (DDF) module in SAP Customer Activity Repository. In this they differ from other time series (see Time Series).

Implementation Considerations

Prerequisites

Several prerequisites must be fulfilled before you can access and use the SAP HANA content for SAP Customer Activity Repository, including the virtual data models for UDF.

For more information, see the following:

Delivery Units

The VDMs are part of the SAP HANA content for the UDF and DDF modules.

The SAP HANA content is provided in delivery units (for example, HCO_DDF_UDF). Each delivery unit is shipped via an SAP HANA Transport Container (sometimes referred to as ABAP TLOGO object; for example, /DMF/HCO_DDF_UDF).

The SAP HANA Transport Containers for UDF and DDF are shipped in the RTLDDF 200 software component version.

Note Note

  • You can view and manage delivery units in SAP HANA studio, using the SAP HANA Modeler perspective.

  • You can find SAP HANA Transport Containers in your ABAP system using transaction SE80 and searching for objects named “/<namespace>/HCO_*” (for example, /DMF/HCO_*).

End of the note.
