Which version of SAP BW is necessary for the hybrid approach using SAP Business Data Cloud?

The correct choice for the hybrid approach using SAP Business Data Cloud is SAP BW 7.5. This version introduced several enhancements that support hybrid data management and integration, particularly with SAP Business Data Cloud. SAP BW 7.5 is designed to allow for integrated data processing between on-premises SAP BW and cloud solutions, thus positioning it favorably for companies looking to leverage both environments effectively.

Additionally, SAP BW 7.5 features capabilities such as advanced data modeling and seamless integration with SAP HANA, enabling more sophisticated analytics and reporting functionalities. The version serves as a bridge enabling users to transition towards cloud-based analytics while still maintaining their on-premise data solutions, making it ideal for hybrid models where real-time analysis and data integrity are critical.

Other versions, such as SAP BW 7.0, lack the necessary enhancements and integrations introduced in 7.5, while BW/4HANA is tailored specifically for cloud-native architectures and not hybrid scenarios. Similarly, BW 8.0 does not exist as of the cutoff date and is not relevant for this context. Thus, SAP BW 7.5 stands out as the essential version for implementing a hybrid approach with SAP Business Data Cloud.
