You need to integrate data from SAP S/4HANA and legacy ERP to SAP IBP.

SAP IBP integrates with SAP S/4HANA and legacy ERP systems to transfer master and transactional data, using specific tools designed for cloud-based planning.

Option A: SAP Cloud Integration for Data ServicesThis is correct. SAP Cloud Integration for Data Services (CI-DS) is the primary tool for integrating SAP IBP with S/4HANA and legacy systems. It supports batch data transfers (e.g., master data, key figures) via predefined templates, as per SAP IBP’s integration framework.

Option B: SAP Smart Data IntegrationThis is correct. SAP Smart Data Integration (SDI), part of SAP HANA, enables real-time or batch integration from S/4HANA and legacy ERPs to SAP IBP, particularly for complex data mappings, a supported method in SAP’s documentation.

Option C: Core InterfaceThis is incorrect. Core Interface (CIF) is used in SAP ECC/APO, not SAP IBP. IBP relies on cloud-based tools like CI-DS, not ECC’s CIF.

Option D: Real-time IntegrationThis is incorrect. "Real-time Integration" is a concept, not a specific tool. While SDI supports real-time, it’s the tool itself (B), not a standalone option.

Thus, A and B (CI-DS and SDI) are the correct integration tools for SAP IBP, per official integration guides.
