SAP BTP (Business Technology Platform) is the tool used to automatically replicate data from SAP S/4HANA to SAP Service Cloud V2. SAP BTP provides integration services, such as SAP Integration Suite, to enable seamless data replication and synchronization between the two systems. According to SAP documentation, 'SAP BTP facilitates automatic data replication between SAP S/4HANA and SAP Service Cloud V2 using standard integration flows.'

Data Workbench (A) is used for manual data imports/exports. SAP Build (B) is for app development, not data replication. SAP WorkZone (C) is a collaboration tool, not for data integration.
