Information About Data Transfer via ODP from ABAP CDS Views

You can use Operational Data Provisioning (ODP) to connect a SAP system as the source system to the SAP BW system. The ODP context for ABAP CDS views (ABAP_CDS) is used to provide ABAP Core Data Services views (ABAP CDS views) with the corresponding analytics annotations for use in SAP BW. In particular, this allows you to access correspondingly annotated ABAP CDS views from SAP S/4HANA and SAP S/4HANA Cloud. If the ABAP CDS view contains the required annotations, you can use the view for full extraction and data access or for delta extraction. Communication takes place using RFC or HTTP (for SAP S/4HANA Cloud).

Prerequisites

SAP systems that provide ABAP CDS views for SAP BW using the Operational Data Provisioning Framework must have at least one of the following release levels:

For Full Extraction	For Delta Extraction
SAP NetWeaver 7.4 SPS08	SAP NetWeaver 7.5 SPS05
SAP NetWeaver 7.5 (we recommend SPS02)	SAP BW/4HANA 1.0 SPS01
SAP BW/4HANA	SAP BW/4HANA 1.0 SPS01

Analytics Annotations for ABAP CDS Views

The ABAP CDS views allow extraction using the analytics annotations:

Full extraction and query-type access (direct access)

The following annotations make it possible for an ABAP CDS view to be available for full extraction or for the data access:

@Analytics.dataCategory
@Analytics.dataExtraction.enabled

Delta Extraction

For delta extraction, the following additional annotations are available:

Analytics.dataExtraction.delta.byElement.name
Analytics.dataExtraction.delta.byElement.maxDelayInSeconds
Analytics.dataExtraction.delta.byElement.detectDeletedRecords

Note
We recommend only using this annotation if there is no other way of determining the deltas from the underlying source tables, and after thorough performance tests have taken place.
Analytics.dataExtraction.delta.byElement.ignoreDeletionAfterDays

For detailed information about the annotations, see the documentation for Analytics Annotations.

Supported CDS Views in SAP S/4HANA and SAP S/4HANA Cloud

For detailed information about ABAP CDS views supported for extraction and replication, see the following documentation:

Real-Time Replication

Delta extraction can also run as real-time replication in streaming mode if the data transfer process is contained in a process chain in streaming mode. The chain will then start when it is notified by the delta queue (ODQ).
