Announcing Public Preview of the SAP CDC solution in Azure Data Factory and Azure Synapse Analytics

UPDATE! We've launched the new SAP connector in ADF today, June 30, 2022, and updated the blog post below accordingly.


For decades, companies have relied on Microsoft and SAP software to run their most mission-critical operations. Today, we’re excited to launch the public preview of SAP Change Data Capture (CDC) in Azure Data Factory (ADF) and Azure Synapse Analytics. Combining a new data connector with predefined data flow templates, this solution streamlines the integration of SAP data within core Azure services like Azure Synapse Analytics and Azure Machine Learning. 


The new SAP ODP connector leverages SAP Operational Data Provisioning (ODP) framework, which is an established best practice for data integration within SAP landscapes. ODP provides access to a wide range of sources across all major SAP applications and comes with built-in CDC capabilities. In combination with the predefined data flow templates to process and update the changed records to any sink, this makes SAP data integration into Azure very much straight forward.




For many of our customers, SAP systems are critical to their business operations. As organizations mature, become more sophisticated, and graduate from using only descriptive analytics to adopting more predictive/prescriptive analytics, they want to combine their SAP data with non-SAP data in Azure, where they can leverage the advanced data integration and analytics capabilities to generate timely business insights. ADF is a data integration (ETL/ELT) Platform as a Service (PaaS) and, for SAP data integration, ADF currently offers six connectors: 




These connectors can only extract data in batches, where each batch treats old and new data equally without identifying data changes (“batch mode”). This extraction mode isn’t optimal when dealing with large data sets, such as tables with millions or even billions of records, that change often. To keep your copied SAP data fresh, frequently extracting it in full is expensive and inefficient.  


There’s a manual and limited workaround to extract mostly new or updated records, but this process requires a column with timestamp or monotonously increasing values, and continuously tracking the highest value since last extraction (“watermarking”). Unfortunately, some tables have no column that can be used for watermarking and this process can’t handle deleted records. 


Our customers have been asking for a new connector that can extract only data changes (inserts/updates/deletes = “deltas”), using CDC capabilities provided by SAP systems (“CDC mode”). To meet this need, we’ve built a new SAP connector leveraging SAP ODP framework. This new connector can connect to all SAP systems that support ODP, such as ECC, S/4HANA, BW, and BW/4HANA, directly at the application layer or indirectly using SAP Landscape Transformation (SLT) replication server as a proxy. The connector can fully or incrementally extract SAP data that includes not only physical tables, but also logical objects created on top of those tables, such as Extractors or ABAP Core Data Services (CDS) views, without watermarking. 


How does it work? 

Our new SAP ODP connector can extract various data source (“provider”) types, such as: 

  • SAP extractors, originally built to extract data from SAP ECC and load it into SAP BW 
  • ABAP CDS views, the new data extraction standard for SAP S/4HANA 
  • InfoProviders and InfoObjects in SAP BW or BW/4HANA 
  • SAP application tables, when using SLT replication server as a proxy 

These providers run on SAP systems to convert full/incremental data into data packages in Operational Delta Queue (ODQ) that can be consumed by ADF pipelines leveraging SAP ODP connector ("subscriber"). 


You can run ADF copy activity with SAP ODP connector on self-hosted integration runtime (SHIR) to extract the raw SAP data and load it into any destination, such as Azure Blob Storage or Azure Data Lake Store (ADLS) Gen2, in CSV/Parquet format, essentially archiving/preserving all historical changes. With the available data flow templates, it becomes straight forward to design and run ADF data flow activity on Azure Databricks/Apache Spark cluster (Azure IR) to transform the raw SAP data, merge all changes, and load the result into any destination, such as Azure SQL Database or Azure Synapse Analytics, in effect replicating your SAP data. 




If you load the merged result into ADLS Gen2 in Delta format (Delta Lake/Lakehouse), you can query it using Azure Synapse serverless SQL/Apache Spark pool to produce snapshots of SAP data for any specified periods in the past (“time-travel”). ADF pipelines containing these copy and data flow activities can be auto-generated using ADF templates and frequently run using ADF tumbling window triggers to replicate SAP data into Azure with low latency and without watermarking.




Today, June 30, 2022, we are releasing our SAP CDC solution in ADF including SAP ODP connector and data replication templates for public preview.
