SAP C_BW4H_2505 Exam - Topic 9 Question 3 Discussion

To load data directly into SAP Datasphere (formerly known as SAP Data Warehouse Cloud) core tenant using delta mode via S-API Extractors, certain prerequisites must be met. Let's evaluate each option:

Option A: Real-time access needs to be enabled. Real-time access is not a prerequisite for delta mode loading. Delta mode focuses on incremental data extraction and loading, which does not necessarily require real-time capabilities. Real-time access is more relevant for scenarios where immediate data availability is critical.

Option B: A primary key needs to exist. A primary key is essential for delta mode loading because it uniquely identifies records in the source system. Without a primary key, the system cannot determine which records have changed or been added since the last extraction, making delta processing impossible.

Option C: Extractor must be based on a function module. While many S-API Extractors are based on function modules, this is not a strict requirement for delta mode loading. Extractors can also be based on other mechanisms, such as views or tables, as long as they support delta extraction.

Option D: Operational Data Provisioning (ODP) must be enabled. ODP is a critical prerequisite for delta mode loading. It provides the infrastructure for managing and extracting data incrementally from SAP source systems. Without ODP, the system cannot track changes or deltas effectively, making delta mode loading infeasible.

SAP Datasphere Documentation : Outlines the prerequisites for integrating data from SAP source systems using delta mode.

SAP Help Portal : Provides detailed information on S-API Extractors and their requirements for delta processing.

SAP Best Practices for Data Integration : Highlights the importance of primary keys and ODP in enabling efficient delta extraction.

In conclusion, the two prerequisites for S-API Extractors to load data into SAP Datasphere core tenant using delta mode are the existence of a primary key and the enabling of Operational Data Provisioning (ODP) .
