The 'Generate Dataflow' function in SAP BW/4HANA automates the creation of a persistent data staging layer from a virtual object like an Open ODS View. The system wizard generates the fundamental objects required for this data acquisition process. These core components are:

1. A Data Source to define the extraction from the source of the Open ODS View (the SAP HANA table).

2. A Data Store object (advanced) to serve as the persistent data target.

3. A Transformation to map the fields and provide the framework for adding the enrichment logic between the Data Source and the aDSO.

C. Composite Provider: This is a virtual data mart layer object used for combining data for reporting and analysis; it is not part of a data loading flow.

E. Info Source: While the wizard provides an option to include an InfoSource for architectural decoupling (LSA++), it is not a mandatory component of the core data flow, which can be created without it.

1. SAP Help Portal for SAP BW/4HANA: In the application help for "Modeling Data Warehousing Processes

" the section "Generating Data Flows" states: "For an Open ODS view

the system proposes creating a DataStore object (advanced) as the target

a DataSource as the source

and a transformation together with a data transfer process." This directly confirms the creation of objects A

B

and D.

Section 6.4.2

"Generating Data Flows

" describes this function. It details that when persisting data from an Open ODS view

the wizard's primary proposal is to create a DataSource

an advanced DataStore Object (aDSO)

and the corresponding transformation and DTP.

3. SAP Training Courseware BW450 (SAP BW/4HANA Modeling). Unit 4

Lesson "Creating a Data Flow". The exercises and content demonstrate that the simplest persistent data flow generated from a source object consists of a DataSource

a Transformation

and a DataStore Object (advanced).
