SAP BW4HANA improved data reporting processes significantly. Performance on HANA database is good. Well-built data models ensure consistent and fast reporting. Reusable models enhance efficiency, even for SaaS services. In-memory computing, especially since HANA, has greatly improved performance in data analysis tasks. It eliminates the need for complex optimizations like creating indexes or aggregates. Queries that once took minutes now run in seconds, enabling real-time reporting, especially for SAP ECC on HANA. SAP BW4HANA's integration capabilities are streamlined with a simplified architecture and more virtual layers. You can directly load data into optimized layers, reducing the need for extra storage. The introduction of Open ODS Views allows for additional logic and master data inclusion, making integration faster and simpler. The learning curve for SAP BW4HANA is much faster now compared to ten years ago, thanks to abundant free resources like documentation, videos, blogs, and learning journeys provided by SAP. It is simpler to learn with these resources available compared to the past when you had to attend courses and rely on books. I would recommend SAP BW4HANA to users looking to implement it, especially if they want to keep their systems on-premise and already have SAP systems. Those with BW on HANA have two choices: BW4HANA or DataSphere, depending on their cloud strategy. If they are advanced in their cloud strategy and want to migrate off-premise, DataSphere is a good choice. However, for a robust solution on-premise or in a private cloud, BW4HANA is an excellent option. Overall, I would rate BW4HANA as a nine out of ten. It performs all necessary data warehouse tasks and offers additional functionalities. We use it traditionally, with complex transformations and models but with less emphasis on real-time processing and third-party sources.
