SAP Ariba Master Data: Overview, Hierarchy & Relationships
TL;DR
- SAP Ariba has 7 master data objects across 5 phases: User, Role (required), Commodity (required), Supplier Master, Catalog, Approval Rule (required), and Integration Model.
- Setup must follow dependency order — User and Role first, then Commodity, then Supplier Master and Catalog, then Approval Rule, and finally Integration Model if S/4HANA integration is needed.
- This article provides the structural map; field-level detail for each object is covered in ARIBA-A02 onward.
