Which of the following activities must you perform to define data replication in SAP Master Data Governance?

Defining and activating the replication model is a crucial step in data replication within SAP Master Data Governance (MDG). The replication model determines how data will be transferred from MDG to the SAP system or other connected systems. It encompasses the specifications about which data entities will be replicated, the direction of data flow, and the method of replication (e.g., real-time, batch).

When this model is defined and activated, it ensures that the changes made in the master data within MDG are accurately reflected in other systems, facilitating data consistency and integrity across the enterprise landscape. This activity is fundamental because without a correctly defined and activated replication model, the master data cannot be effectively synchronized, leading to potential discrepancies in data across platforms.

The other activities, while they might seem related to data governance, do not directly pertain to the replication process itself. User access levels primarily manage permissions rather than data flow, creating a backup of existing data is a good practice for data management but not a requirement for defining replication, and adjusting data governance policies is a broader organizational activity that does not specifically focus on data replication. Hence, focusing on the replication model is essential for ensuring successful data synchronization in an MDG environment.
