Part 2 – SAP S/4HANA Cloud Data Integration Overview
After getting an overview and understanding of how Virtual Data Models (VDM) and ABAP Core Data Services (ABAP CDS Views) work in SAP S/4HANA, and the requirements needed for a CDS View to be extractable in my colleague Michael Sanjongco’s blog post Part 1 – SAP S/4HANA Cloud Data Integration to power your Intelligence Enterprise.
This blog will briefly explain the different components which play a role in exposing data from SAP S/4HANA Cloud, and the different options to connect SAP S/4HANA to target systems like SAP BW/4HANA, SAP Data Intelligence, and SAP Data Warehouse Cloud to be able to extract data to them, and achieve your extensibility and analytics scenarios.
Explaining the extraction mechanism from a bottom-up approach as shown in the Architectural Overview (figure 1):
- Application Tables are the database tables that hold all business/configuration data. Data cannot be extracted directly from them
- Internal CDS View Models are views built on top of Application Tables and/or other CDS Views for data modeling purposes
- CDS Extraction views are the extraction-enabled CDS Views that are built on top of associations of Application Tables and/or other CDS Views, depending on what the CDS View itself is exposing. They are used for data extraction from SAP S/4HANA
- Extraction runtime is the middleware between the CDS Views and target systems. It contains different engines like Operational Data Provisioning (ODP)/Operational Delta Queue (ODQ), Change Data Capture (CDC), and Reconstruction. They are responsible to convert, expose and transfer the data to the respective API which the target system can communicate with; those are reflected both in the communication scenarios configured in SAP S/4HANA Cloud, and the respective connection type/configuration on the target system as it will be explained in detail in the next blogs
The table below shows the different integration scenarios, their corresponding communication scenario(s), connection types, best practices to guide you on how to set up the integration scenario, and documentation of different applications that can be used in target systems to extract SAP S/4HANA Cloud Data from:
|Scenario||Target System||Communication Scenario||API||Protocol||Scope Item||Connection Types||Documentation|
|SAP_COM_0042||SOAP (Simple Object Access Protocol)||Remote Function Call (RFC)||35D||
SAP Business Warehouse powered by SAP HANA
|2||SAP Data Intelligence||SAP_COM_0532||ABAP Pipeline||Websocket RFC||53M||ABAP Connection||
|SAP_COM_0531||Cloud Data Integration (CDI)||oData||Cloud Data Integration||Cloud Data Integration Consumer|
|3||SAP Data Warehouse Cloud||SAP_COM_0532||ABAP Pipeline||Websocket RFC||53L||S/4HANA Cloud (Recommended)|
|SAP_COM_0532||ABAP Pipeline||Websocket RFC||SAP ABAP connection (Supports Data Flows only)|
|SAP_COM_0531||CDI||oData||Cloud Data Integration|
You can use Data Flows and Remote Tables in SAP Data Warehouse Cloud to preview the data exposed by the ABAP CDS Views before extracting them. As for SAP Data Intelligence, you can use the Metadata Explorer to have a metadata analysis for the ABAP CDS Views (e.g. ABAP CDS Views fields and field types).
In the next blogs, we will discuss in detail each of the S/4HANA Cloud Integration scenarios, how you can set them up and make the best use of them.
We would be happy to receive your feedback in the blog post comments section below and answer all your questions under the SAP S/4HANA Cloud Q&A area.
See you in our next blog posts.
