SAP MM Master Data: Overview, Hierarchy & Relationships
TL;DR
- SAP MM master data consists of nine objects across five phases — Material Master and Vendor Master (Business Partner) are the only mandatory ones; the rest are optional depending on business requirements.
- Configuration must follow the dependency order: Material Master → Vendor Master → Classification → Batch Master → Purchasing Conditions.
- Each object in this article links to a dedicated L2-A article for detailed field-level guidance.
