SAP BW/4HANA: Modeling, Simplified

Why SAP BW/4HANA is the Future of Data Modeling

Switching to SAP BW/4HANA comes with big changes—especially in how data modeling works. If you're used to SAP BW, you might wonder how classic objects compare to SAP BW/4HANA modeling objects.

This blog breaks it all down in simple terms.

Key Takeaways

  • Simplified Data Modeling – Fewer objects mean less complexity.
  • Faster Performance – Designed for SAP HANA, ensuring high speed.
  • Better Flexibility – Supports real-time analytics and virtualization.
  • Easier Maintenance – No more outdated or redundant objects.
  • Future-Proof Solution – Aligns with modern data warehouse trends.

SAP BW vs. SAP BW/4HANA: The Big Difference

SAP BW was built on relational databases and evolved over time. This led to a large number of modeling objects. Each object had a specific function, making the system complex.

SAP BW/4HANA changes that. It offers a cleaner, more efficient structure by reducing the number of objects while improving their capabilities.

Think of it like moving from a cluttered toolbox to a streamlined set of multi-functional tools. Instead of juggling multiple objects, you now work with fewer but more powerful ones.

SAP BW/4HANA Modeling Objects: What’s New?

SAP BW/4HANA has four main modeling objects:

  1. InfoObjects – Used for master data storage.
  2. Open ODS Views – Enable virtualization of external data sources.
  3. Advanced DSOs (aDSOs) – Handle data persistency and can replace classic DSOs and InfoCubes.
  4. CompositeProviders – Act as a logical layer, combining different data sources.

Each of these objects replaces multiple older objects from SAP BW, making the system much easier to manage.


SAP BW Modeling Objects: The Old Way

SAP BW required several different objects to achieve the same goals:

  • InfoCubes – Used for multidimensional storage.
  • DSOs (DataStore Objects) – Stored transactional data.
  • InfoSets – Created joins between multiple DSOs.
  • MultiProviders – Combined multiple InfoProviders.
  • Virtual Cubes – Allowed for real-time reporting.
  • Hybrid Providers – Mixed real-time and stored data.
  • Persistent Storage Areas (PSAs) – Acted as temporary storage.

As you can see, SAP BW had many overlapping objects. This increased complexity, slowed down performance, and required more maintenance.


How SAP BW/4HANA Simplifies Data Modeling

The biggest change in SAP BW/4HANA is consolidation. Instead of working with seven or more different objects, you now use just four.

For example:

  • Advanced DSOs (aDSOs) can function as DSOs or InfoCubes, depending on the settings.
  • CompositeProviders replace MultiProviders and InfoSets by offering a flexible way to integrate data.
  • Open ODS Views allow for real-time access to external sources, eliminating the need for Virtual Cubes.

This simplification reduces development time, increases efficiency, and makes maintenance much easier.


Why You Should Upgrade to SAP BW/4HANA

If you're still using SAP BW, you might be hesitant about switching. But staying on legacy technology has risks:

  • Higher Maintenance Costs – Managing outdated objects takes time and effort.
  • Slower Performance – SAP BW wasn't built for modern in-memory computing.
  • Limited Flexibility – You need more objects to do the same work.
  • Future Compatibility Issues – SAP is shifting its focus to SAP BW/4HANA, meaning fewer updates for SAP BW.

By upgrading to SAP BW/4HANA, you ensure your data warehouse remains efficient, future-ready, and cost-effective.

Greenfield vs. Brownfield: Which Migration Approach is Best?

When moving to SAP BW/4HANA, you have two options:

Greenfield Approach (Start Fresh)

  • Best for companies building a new data warehouse.
  • Lets you take full advantage of SAP BW/4HANA features.
  • Avoids legacy system issues.

Brownfield Approach (Migrate Existing Data)

  • Ideal for businesses with a large SAP BW setup.
  • Helps retain valuable historical data.
  • Requires a strategy to convert old objects to new ones.

Choosing the right approach depends on your business needs, budget, and long-term goals.


Key Benefits of SAP BW/4HANA

1. Faster Performance

SAP BW/4HANA is optimized for SAP HANA, allowing real-time processing. This means faster reports, quicker queries, and better overall system performance.

2. Reduced Complexity

With fewer objects, there’s less clutter, making it easier to manage and develop new models.

3. Improved Flexibility

SAP BW/4HANA supports hybrid data models, enabling seamless integration with SAP S/4HANA, SAP Data Intelligence, and cloud storage solutions.

4. Lower Costs

Fewer objects and a streamlined architecture mean lower maintenance costs and better resource utilization.

5. Future-Proof Investment

SAP BW/4HANA aligns with modern data warehousing trends, ensuring your business stays ahead in a rapidly changing landscape.


How to Prepare for the Transition

If you're thinking about migrating to SAP BW/4HANA, here’s a simple roadmap to help:

  1. Assess Your Current Setup

    • Identify existing SAP BW objects.
    • Determine which can be converted and which need to be replaced.

  2. Choose a Migration Strategy

    • Decide between Greenfield or Brownfield.

  3. Clean Up Your Data

    • Remove unused objects and outdated data.

  4. Train Your Team

    • Ensure your team understands SAP BW/4HANA modeling concepts.

  5. Test Before Going Live

    • Run pilot projects before full migration.

By following these steps, you can ensure a smooth and efficient transition.


Final Thoughts

SAP BW/4HANA is the future of SAP data warehousing. It simplifies data modeling, improves performance, and reduces maintenance effort.

If you're still using SAP BW, now is the time to start planning your migration. With faster processing, lower costs, and greater flexibility, SAP BW/4HANA is a smart investment for any data-driven business.
