OCI (Open Catalog Interface)
OCI – The Standard Interface for Catalog Integration
Digitalize your procurement with SAP's established OCI standard
OCI (Open Catalog Interface) has been the standard interface for catalog integration in ERP systems since 1998. It enables external supplier catalogs to be integrated directly into SAP SRM or other systems – without disruption.
OCI: The Data Superhighway Between Buyer and Supplier
OCI is the international standard for direct catalog integration into ERP systems. With OCI, procurement officers access supplier catalogs without leaving the ERP system. A secure, fast, and proven solution for B2B procurement.
How OCI Simplifies Procurement
From catalog selection to order confirmation
Catalog Offering (Browse)
The procurement officer launches an OCI browser from the ERP (e.g., SAP SRM). OCI directs him to the supplier catalog where he browses and selects products.
- ERP-integrated
- Session management
- User context transfer
Shopping Cart Return (Hook URL)
The shopping cart is returned to the ERP via Hook URL. Prices, availability, and attributes are validated immediately.
- Real-time pricing logic
- Inventory check
- Attribute mapping
Catalog Upload
Suppliers can also upload structured catalogs (OCI format, XML, Excel). The ERP integrates them automatically into catalog search.
- Batch upload
- Schema validation
- Change detection
Governance & Compliance
Procurement officers and administrators control which catalogs are released, block products, and monitor usage and spending.
- Release workflows
- Audit trail
- Spend control
