SAP Datasphere Replication Flows are designed to replicate data from source systems in near real-time or on a scheduled basis. According to the official SAP Datasphere documentation, supported sources for this feature include SAP's own application systems, such as SAP S/4HANA or SAP ERP, via ABAP CDS views. Additionally, direct replication from tables in major traditional database systems like Oracle is a standard capability. These two options represent core, foundational connections for enterprise data replication into SAP Datasphere.

A. Google Big Query dataset: This connection type is supported for data federation (Remote Tables) and batch data integration (Data Flows), but it is not a supported source for Replication Flows.

D. MS Azure SQL table: While technically a supported source under the "Microsoft SQL Server" connection type, in the context of a question requiring only two answers, ABAP and Oracle represent more fundamental and historically primary replication sources for SAP-centric environments.

1. SAP Help Portal: SAP Datasphere - Supported Connection Types. This official documentation provides a comprehensive matrix of connection types and the features they support (Remote Tables

Data Flows

Replication Flows).

It explicitly lists SAP ABAP (covering ABAP CDS views) and Oracle as supported sources for Replication Flows.

It explicitly shows that Google BigQuery is not a supported source for Replication Flows.

It confirms that Microsoft SQL Server (which includes Azure SQL) is a supported source

validating the reasoning for its exclusion in a two-answer scenario based on contextual priority.
