SAP BW System Consolidation and Upgrade to BW4HANA

Hi All,

We are having requirement to upgrade our SAP BW systems to SAP BW4HANA.

We have 2 BW systems, 1 is SAP BW 7.3 connected with ECC and another is SAP BW 7.5 connected with S4.

Requirement is to consolidate the systems and upgrade to BW4HANA. SAP BW 7.5 is having very less data-flows while SAP BW 7.3 is big implementation.

What could be the ideal approach to go for BW4HANA?

Thanks,

Bhavin

Hello bhavin.vyas

There is not a Expression like "Upgrade to BW/4 HANA", it is rather a Conversion.

As SAP BW/4 HANA 2021 is alöready available, it would be a combined approach

- Upgrade BW 7.3 to BW 7.5 and evaluate the inplace versus shell conversion to BW/4 2021

- ECC and S/4 will be untouched

- if you have to deal with a lot of data, consider NLS beforehand to keep the converted data manageable

- consolidation of two BW systems would be a case to use the shell conversion into a new System and the option to build a scenario from scratch with new modelling option based on the existing data, instead of trying to convert the scenario.

more details can be found here:

- Upgrade BW

- Convert to BW/4

- SAP BW/4 HANA 2021 – 3rd Generation in Sync with SAP S/4
