SAP Master Data Integration (MDI) is a service on the SAP Business Technology Platform designed to ensure master data consistency across the SAP Intelligent Suite. This consistency is foundational for executing SAP's core end-to-end (E2E) business processes. MDI is based on the SAP One Domain Model, which provides aligned data structures for key master data objects. The primary E2E processes that MDI is geared towards are Lead to Cash (customer/product data), Source to Pay (supplier/product data), and Recruit to Retire (workforce data), which is represented here by "Recruit to Hire". These processes span multiple applications (e.g., S/4HANA, Ariba, SuccessFactors) and rely on MDI for a single, consistent view of master data.

C. Order to Procure: This is a transactional sub-process within the broader "Source to Pay" end-to-end process, not one of the four core E2E processes itself.

D. Manufacture to Build: This describes a specific activity within the "Design to Operate" end-to-end process, which is another core process but is not listed as an option.

This document explicitly names the core processes that MDI supports. (Accessed under SAP Business Technology Platform documentation).

2. SAP Help Portal, What Is SAP Master Data Integration?: "SAP Master Data Integration is the central entry point to create, read, and update master data in an integrated and hybrid system landscape. It ensures the consistency of master data across the Intelligent Suite." This reference establishes the fundamental purpose of MDI in the context of the Intelligent Suite's processes.
