Question Regarding CDC Support for SAP on AWS

Yes, AWS supports Change Data Capture (CDC) implementation for SAP systems through multiple approaches:

1. AWS Database Migration Service (AWS DMS) supports CDC for SAP ASE databases. For ongoing CDC replication, DMS runs dbcc logtransfer and dbcc log commands to read data from the transaction log. AWS DMS supports both full load and CDC methods to migrate historic data and ongoing changes with near-zero latency from on-premises to AWS Cloud.

2. AWS Glue OData connector for SAP uses the SAP ODP (Operational Data Provisioning) framework and OData protocol for data extraction, which supports change data capture through the Operational Delta Queues (ODQ) mechanism. This enables incremental data transfer from SAP sources using delta tokens. The ODP framework supports various SAP data sources including SAP data extractors, ABAP CDS views, SAP BW, BW/4 HANA sources, and HANA information views in SAP ABAP sources.

3. Partner solutions like Fivetran offer fully managed SAP ERP on HANA connectors that replicate SAP ECC and S/4 HANA data using low-impact CDC. Fivetran's solution connects via the NetWeaver application layer and supports various SAP-specific features like cluster tables, pool tables, and long text tables.

For SAP versions, the supported systems include:

• SAP ASE (Adaptive Server Enterprise)
• SAP ECC and S/4 HANA
• SAP BW and BW/4 HANA
• SAP ABAP sources with HANA information views

AWS offers various integration options for SAP data extraction including AWS DMS, AWS Glue, and partner solutions that can be selected based on your specific requirements for CDC implementation.
