What must you do after upgrading SAP Master Data Governance to SAP S/4HANA regarding system landscape integration?

After upgrading SAP Master Data Governance (MDG) to SAP S/4HANA, it is essential to upgrade Data Replication to Service-/SOA-based communication. This transition is vital because SAP S/4HANA emphasizes a more modern architecture that leverages service-oriented architecture (SOA) principles. SOA enables seamless and efficient data communication between systems and allows for better integration with other SAP and non-SAP applications.

The upgrade to SOA-based communication also ensures that the data replication processes are optimized for performance and innovation in the S/4HANA environment. This approach not only enhances the data flow between systems but also aligns with best practices for managing master data in a cloud and service-oriented environment.

Maintaining legacy methods of data replication could lead to inefficiencies and potential issues with data consistency, which is why this upgrade is a critical step in the post-upgrade process for ensuring a robust and future-proof system landscape.
