Planning Your Move to SAP BW/4HANA

Author, Matt Sisley, itelligence UK

Why you need to move to SAP BW/4HANA

If you are running SAP BW then the chances are this is a business critical system. Most businesses running SAP BW rely on it for day-to-day critical decision making. Once they are implemented, SAP BW systems are generally rock solid but it stands to reason that if it is business critical, you need to make sure you are always running a supported version.

Did you know that SAP BW 7.3 and SAP BW 7.4 are going out of support at the end of 2020? Did you also know that SAP are not offering extended support? If you are running one of these platforms then you need to be making plans to move to SAP BW/4HANA now.

SAP BW/4HANA

When you start making these plans the first step is to understand more about SAP BW/4HANA. SAP BW/4HANA 2.0 is supported to the end of 2024 and will continue to receive enhancements and upgrades. There are already lots of good reasons for moving to SAP BW/4HANA.

 

  • SAP BW/4HANA is designed to deliver a modern packaged data warehouse. There are some significant enhancements over earlier editions of SAP BW.
  • SAP BW/4HANA is highly optimised for SAP HANA meaning it is faster than earlier versions of SAP BW – even those running on SAP HANA.
  • Every aspect of data modelling is simplified with fewer object types, fewer data source types, reduced staging of data, new features for modelling non-SAP data sources and more intuitive development interfaces.
  • SAP data sources are now accessed through Operational Data Provision and there is new business content for SAP sources such as SuccessFactors.
  • Data from non-SAP data sources is replicated to SAP BW/4HANA with SAP HANA Smart Data Integration.

If you want to understand more about SAP BW/4HANA (2.0) then read this excellent blog by my colleague David Bradley on the itelligence website.

What you need to think about when planning your move

Similar to SAP S/4HANA there is a simplification list for SAP BW/4HANA. But unlike SAP S/4HANA there is no option to run these features in “Compatibility mode” – if you have items on your simplification report you must deal with them as part of your SAP BW/4HANA move. Some issues mean making changes outside of your SAP BW system.

  • SAP BEx Analyser, SAP Web Application Designer and the SAP BW Java stack are deprecated. That means that if you are moving to SAP BW/4HANA you will need a reporting/analytics tools to use the data in your BW system. The good news is that if you use SAP Business Objects or SAP Analytics Cloud they can still connect to your SAP BEx queries in the same way as they do now.
  • SAP BPC 10, Analysis Process Designer (APD), BW-IP and BW-BPS are not supported in their current form and require manual steps to convert.
  • SAP BW Accelerator is no longer supported. This is a simple one – there is no need for BW Accelerator given SAP BW/4HANA’s performance.
  • Some Netweaver add-ons are not supported.

You will also need to convert all your existing content to the new types if you are using older object types like InfoCubes and MultiProviders or older 3.x data sources.

This means that in many cases, a SAP BW/4HANA conversion is a Brownfield process. A Brownfield implementation is where a new system is created and built to deliver the same outcomes but with a different technical implementation. There are some tools available which in some cases can help to accelerate a Brownfield implementation.
