In a fast-paced digital world, businesses are increasingly recognising the need to modernise their data management systems. One significant shift is the transition from SAP Business Warehouse (SAP BW) to SAP Datasphere and SAP . This move is not just a technological upgrade but a strategic decision that can lead to greater levels of efficiency, scalability, and innovation.

In my role as senior Data and Analytics Consultant at NTT DATA Business Solutions, I have gained expertise working across SAP BW implementations in local and global organisations. In this blog, I will explore the motivations for this change, the benefits it offers, the steps involved in making this strategic move and the option to transition existing investments of SAP BW into the cloud.

The Need for Modernisation

For years, SAP BW has been a cornerstone for many organisations’ data management strategies. However, as data volumes grow and the need for real-time analytics becomes more critical, traditional on-premise systems like SAP BW face several limitations. These include challenges in scalability, integration with modern data sources, and the ability to support advanced analytics and integrate AI capabilities.

SAP BW – Current Challenges 

SAP Datasphere, on the other hand, is a Data Warehouse as a Service (DWaaS) offering built on SAP HANA Cloud, with rapid release cycles and seamless integration with existing SAP systems. Its flexibility and scalability make it ideal for modern data environments.

End of Support for SAP BW Releases

As the strategic direction for SAP’s data warehousing and management in the public cloud, SAP Datasphere is set to replace SAP BW solutions.

One of the critical triggers for organisations to consider moving from SAP BW to SAP Datasphere is the end of support for various SAP BW releases.

SAP BW 7.5, for instance, will reach the end of mainstream maintenance by December 31, 2027, with extended maintenance available until December 31, 2030. Similarly, SAP BW/4HANA 2.0 will be supported until December 31, 2025.

These deadlines create a sense of urgency for businesses to transition to more modern and supported platforms. Moving to SAP Datasphere not only ensures continued support but also provides access to the latest innovations in data management and analytics.

Benefits of Moving to SAP Datasphere

1. Scalability and Performance

Unlike on-premise systems, which require substantial investments in hardware and maintenance, SAP Datasphere leverages the cloud’s elasticity to scale effortlessly. This means businesses can scale their data infrastructure up or down based on demand, ensuring optimal performance without the overhead costs.

2. Integration and Interoperability

SAP Datasphere is built to integrate seamlessly with a wide range of data sources, both SAP and non-SAP, on-premises or in the Cloud. This includes integration with SAP S/4HANA, SAP BW/4HANA, and other third-party data sources.

3. Advanced Analytics and AI

With SAP Datasphere, organisations can leverage advanced analytics and artificial intelligence (AI) capabilities. The platform supports real-time data processing and analytics, enabling businesses to gain insights faster and make data-driven decisions. Additionally, SAP’s partnerships with leading AI and data vendors enhance the platform’s capabilities, allowing for more sophisticated data analysis and machine learning applications.

4. Cost Efficiency

Moving to a cloud-based data management solution like SAP Datasphere can result in significant cost savings. Organisations can reduce their capital expenditures on hardware and infrastructure while benefiting from a subscription-based pricing model. This shift from CapEx to OpEx allows for more predictable budgeting and financial planning.

5. Enhanced Security and Compliance

Data security and compliance are paramount in today’s business environment. SAP Datasphere offers robust security features, including data encryption, access controls, and compliance with industry standards and regulations. This ensures that sensitive data is protected and that organisations can meet their regulatory requirements.

Steps to Transition from SAP BW to SAP Datasphere

Transitioning from SAP BW to SAP Datasphere involves several key steps. Here is a high-level overview of the process:

1. Assessment and Planning

Assessment and planning are crucial for a successful migration. This step involves a thorough evaluation of your current SAP BW environment and developing a detailed migration strategy.

In other words, this step involves identifying integration, data models, reports, and processes that need to be migrated and determining the best approach for the transition.

SAP offers a complimentary SAP BW system assessment (BW Move Readiness Check) to help organisations on their transition. Extending on the SAP Readiness Check report, NTT Data offers a free two-day assessment service to analyse the current BW state and the complexity of the landscape to deliver a recommendation of the key next steps and guidance on the BW modernisation journey.

2. Choosing the Migration Method

There are several data warehousing strategies for a smooth transition to the Cloud, which provide flexibility for organisations to modernise their data warehousing landscape while protecting existing investments. Each migration option has its pros and cons.

SAP BW Bridge is a key capability designed to facilitate the transition from SAP BW NetWeaver and SAP BW/4HANA to SAP Datasphere. By using SAP BW Bridge, organisations can gradually transition their data warehousing workloads to the cloud, ensuring a smooth and controlled migration process.

In summary, this is how it works:

  • Data Integration: SAP BW Bridge enables the reuse of SAP BW data structures, transformations, and customisations within SAP Datasphere. This ensures continuity and protects existing investments.
  • Staging and Extraction: SAP BW Bridge provides ABAP-based data extraction and staging capabilities, allowing organisations to continue using their familiar SAP BW processes in the cloud.
  • Hybrid Scenarios: SAP BW Bridge supports hybrid deployment scenarios, where data can be managed both on-premise and in the cloud. This flexibility allows for a phased migration, reducing the risk and complexity associated with a full-scale immediate transition.
  • Operational Data Provisioning (ODP): The bridge leverages ODP for data extraction, ensuring efficient and reliable data transfer from SAP BW to SAP Datasphere.

In this context, there are two primary methods for migrating from SAP BW to SAP Datasphere, SAP BW Bridge: remote conversion and shell conversion.

Remote conversion involves transferring both metadata and data and it is suitable for organisations that want to migrate their entire data landscape and require immediate access to all historical data in SAP Datasphere.

Shell conversion is a faster method as it transfers only metadata (data models, structures…), allowing for a phased migration where data can be moved gradually over time.

By carefully assessing the current environment and recommending the right migration method, NTT Data can set the stage for a successful transition to SAP Datasphere. This strategic move can help organisations unlock new levels of efficiency, scalability, and innovation in data management.

3. Preparing the Environment

Before starting the migration, it is essential to prepare both the source and target environments. This includes, for example, updating the source system to the latest patch level, checking for custom code and creating the necessary connections between the source and target systems. In summary, ensuring that all necessary prerequisites are met. Proper preparation helps minimise potential issues during the migration.

4. Executing the Migration

Once the environment is prepared, the migration process can begin. This means, transferring the metadata and data, and validating the migration. SAP provides detailed guides and tools to support this process, ensuring a smooth transition.

5. Post-Migration Activities

Once the migration is complete, there are several post-migration activities to consider. These include validating the data, optimising the new environment, and training users on the new system. Continuous monitoring and optimisation help ensure that the new SAP Datasphere environment operates efficiently and meets the organisation’s needs.

Our accelerators (SMART Plays) will ensure we deliver on time and without re-inventing the wheel!. ​

To streamline the adoption of SAP Datasphere and ensure timely delivery, we have developed accelerators (SMART Plays) that leverage proven methods and tools. These accelerators enable us to deliver solutions efficiently without the need to start from scratch.
