SAP BW/4HANA

SAP Business Warehouse (SAP BW) is the technological basis for a comprehensive Enterprise Data Warehouse, as well as a business intelligence and planning environment. With SAP BW, you can bring together historical and current data from various systems, model, consolidate and prepare it to make it available to your employees for analysis, reporting and planning.

The latest generation SAP BW/4HANA analyzes huge amounts of data even in real-time. With SAP Business Warehouse, you can create a central source of information for your entire company, providing all parties involved with a uniform, data-based view of your business situation.

SAP BW on anyDB, SAP BW powered by SAP HANA, SAP BW/4HANA - the SAP Business Warehouse portfolio is extremely diverse. The orientation for the future is much clearer: SAP focuses exclusively on SAP BW/4HANA for innovations and further developments. One of the main reasons for the consistent orientation towards SAP BW/4HANA is the significantly higher performance achieved by the HANA in-memory technology compared to conventional databases. Leaner data models, shorter loading times, and modern user interfaces ensure up to 70% faster processes.

What does this mean for the older BW releases? If you have SAP BW 7.5 in use, you're in luck! This version will be supported until 2027. If your BW release is older (for example, 7.3 or 7.4), you need to take action to avoid extended maintenance. This is because mainstream maintenance expires on December 31, 2020.


With SAP BW, you can merge historical and current data from a wide variety of systems, model, consolidate, and prepare it. Create a central information source for your entire company.

Path of the Classic Data Warehouse to SAP BW/4HANA

For companies using an SAP BW release older than 7.5, the end of maintenance in 2027 means that they will have to deal with the migration to SAP BW/4HANA early on. Depending on the initial situation, there are various options for the migration, which vary in their complexity.

It is important to carry out a comprehensive overall assessment in advance of the migration to SAP BW/4HANA. The changeover is not only accompanied by adjustments to data structures and data modeling. It is at least as important to keep an eye on the effects on the front-end side. The SAP Business Explorer (BEx) and traditional BEx tools such as Web Application Designer (Web templates) and Analyzer (workbooks) are no longer supported by SAP BW/4HANA. Instead, data is prepared with SAP Business Objects, Microsoft Analysis for Office, or with the SAP Analytics Cloud.

Migration Paths SAP BW/4HANA

If you have to decide on a method, there is no one optimal method. You have to make the decision based on the initial situation and future requirements. SAP SE recommends various migration methods depending on the Start Release.

 

BW4HANA_Migration_Path


  • A greenfield approach or a completely new implementation means that a completely new SAP BW/4HANA system is implemented. All reporting applications and objects are recreated on the basis of SAP BW/4HANA. Data from the old BW system is not transferred.
  • There are three different migration methods for a system conversion approach. With an in-place conversion, the current BW system is converted to SAP BW/4HANA in the system itself, so to speak. The in-place conversion requires a SAP HANA database, as well as a SAP BW 7.5 with a minimum SP Level 5, and the SAP BW/4HANA Starter Add-on must be installed. This is the only way to convert Transfer Cockpit data flows into BW/4HANA compliant objects.
  • If the remote conversion is used, the first step is to set up a new SAP BW/4HANA system with a new SID. In the next step, data models in the legacy system can be selected and converted to the new SAP BW/4HANA. The data from the objects to be converted is also transferred. In contrast, the shell conversion does not transfer this data to the new SAP BW/4HANA system, but only transfers the converted metadata of the new objects.
  • In scenarios where several SAP BW systems are to be merged into one target SAP BW/4HANA system, the migration method of system consolidation is used.

With regard to the chronological sequence of a migration project, there are different phases, which are illustrated below.

We recommend starting a migration project with a proof of concept or an analysis preliminary project. The aim is to minimize any problems that may arise during the migration phase.
