How SAP BW 7.5 System is Affected by S/4HANA Migration

S/4HANA is the latest ERP suite from SAP that is built on the SAP HANA platform. It offers many benefits such as simplified data model, real-time analytics, intelligent automation, and enhanced user experience. If you are an existing SAP ECC customer, you might be planning to migrate your current system to S/4HANA and enjoy the benefits of the new solution.

However, migrating to S/4HANA is not a trivial task. It involves a lot of technical and functional changes, such as converting your data structures, adjusting your custom code, and optimizing your system performance. Therefore, you need to consider the impact of S/4HANA migration on your other SAP systems, such as SAP BW.

SAP BW is a data warehouse solution from SAP that helps you collect, store, analyze, and report on your business data. If you are an existing SAP BW 7.5 customer, you might be wondering how S/4HANA migration will affect your SAP BW system and what you need to do to prepare for it.

In this blog post, we will explain how S/4HANA migration impacts SAP BW 7.5 system, covering the following topics:

  • The changes in the data sources and extractors for S/4HANA
  • The compatibility and availability of the SAP BW business content for S/4HANA
  • The options and tools for migrating SAP BW 7.5 system to SAP BW/4HANA

Changes in the Data Sources and Extractors for S/4HANA

One of the main impacts of S/4HANA migration on SAP BW 7.5 system is on the data sources and extractors that are used to transfer data from S/4HANA to SAP BW. Data sources are logical views of the data in S/4HANA that can be accessed by SAP BW. Extractors are programs that extract data from data sources and transfer them to SAP BW.

With S/4HANA migration, some of the data sources and extractors in S/4HANA are changed or replaced due to the simplification of the data model and the introduction of new features and functionalities. For example, some of the data sources and extractors based on Logistics Information System (LIS) or CO-PA are no longer available or supported in S/4HANA. Instead, new data sources and extractors based on Operational Data Provisioning (ODP) or Core Data Services (CDS) are introduced.

Therefore, you need to check the compatibility and availability of your existing data sources and extractors in S/4HANA before migrating from ECC to S/4HANA. You can use the Simplification Item Check tool from SAP to check your current system for compliance with the Simplification List for S/4HANA. You can also use the Excel list attached to SAP Note 2500202 – S4TWL – BW Extractors in SAP S/4HANA to get an overview of the status of all SAP BW business content data sources and extractors in S/4HANA.

Depending on the status of your data sources and extractors in S/4HANA, you might need to perform some actions, such as:

  • Whitelisted: The data source or extractor is working or working with limited impact in S/4HANA. You can continue using it without any changes.
  • Generated: The data source or extractor is working but needs to be regenerated in S/4HANA. You can use transaction RSO2 or program RS_BW_POST_MIGRATION in S/4HANA to regenerate it.
  • Not whitelisted: The data source or extractor is not working or not supported in S/4HANA. You need to find an alternative solution, such as using a new data source or extractor, creating a custom data source or extractor, or using a different extraction method.
  • Deprecated: The data source or extractor is no longer relevant or recommended for BW extraction in S/4HANA. You need to find an alternative solution, such as using a new data source or extractor, creating a custom data source or extractor, or using a different extraction method.

Compatibility and Availability of the SAP BW Business Content for S/4HANA

Another impact of S/4HANA migration on SAP BW 7.5 system is on the compatibility and availability of the SAP BW business content for S/4HANA. Business content is a set of predefined data models, data flows, reports, queries, and customizations that are provided by SAP for various application modules and scenarios.

With S/4HANA migration, some of the SAP BW business content for ECC are changed or replaced due to the changes in the data sources and extractors in S/4HANA. For example, some of the SAP BW business content for FI, CO, MM, SD, or PP are no longer available or supported in S/4HANA. Instead, new SAP BW business content for S/4HANA are introduced.

Therefore, you need to check the compatibility and availability of your existing SAP BW business content in S/4HANA before migrating from ECC to S/4HANA. You can use the Excel list attached to SAP Note 2500202 – S4TWL – BW Extractors in SAP S/4HANA to get an overview of the status of all SAP BW business content data sources and extractors in S/4HANA. You can also use the SAP Help Portal to get more information about the new SAP BW business content for S/4HANA.

Depending on the status of your SAP BW business content in S/4HANA, you might need to perform some actions, such as:

  • Activating the new SAP BW business content for S/4HANA using transaction RSA1 or program RSORBCT
  • Adapting your existing SAP BW business content to the new data sources and extractors in S/4HANA using transaction RSA1 or program RSORADJUST
  • Creating your own custom SAP BW business content based on your specific requirements using transaction RSA1 or program RSOR

Conclusion

S/4HANA migration has a significant impact on SAP BW 7.5 system and requires careful planning and preparation. You need to check the compatibility and availability of your data sources, extractors, and business content in S/4HANA and perform some actions accordingly. You also need to choose the right option and tool for migrating your SAP BW 7.5 system to SAP BW/4HANA based on your specific situation and requirements.
