Discover CDS View Based Extractors from SAP S/4HANA Cloud

Overview

Data extraction and replication makes it possible to transfer data from an SAP source system, such as SAP S/4HANA Cloud, to the target system SAP BW/4HANA. This includes the metadata description of the source data that is to be transferred to SAP BW/4HANA, as well as delta extraction mechanisms.

CDS View based extractors are available from SAP S/4HANA Cloud 1905 CE.

Discover

CDS View based extractors (CDSV extractors) are released CDS Views that are enabled for data extraction (full) by the annotation @Analytics.dataextraction.enabled: true.

CDSV extractors that support delta extraction contain the annotation @Analytics.dataextraction.delta

CDSV extractors could be found using the View Browser app in a SAP S/4HANA Cloud system or SAP S/4HANA Cloud Trial system.

The steps to find the list of CDSV extractors are mentioned below:

  • In the SAP S/4HANA Cloud system, choose the App Finder and search for the View Browser app.
  • Open View Browser app from the search results.

  • Change the Standard variant to Released Views variant.

  • Enter the search text @Analytics.dataextraction.enabled:true in the Search box and press Enter.
  • Choose Document Export button to download the list of CDSV extractors.

Conclusion

CDS View based Extractors are now available and can be discovered via View Browser app. CDS View based extractors are not a 100% match with the classical BW extractors due to the change in the data model in SAP S/4HANA. Hence, alternative CDS View based extractors cannot be listed for each classical extractor. The alternate extractors could be derived by closely checking the details of the CDS View based Extractors in the View Browser app and via the business documentation.
