SAP S/4HANA ↔ Coupa — Requisitions, POs + Invoice Sync
The SAP S/4HANA ↔ Coupa connector by ERPPlugs sends Coupa-approved requisitions to S/4HANA MM as Purchase Orders, matches Coupa invoices against S/4HANA Goods Receipts three-way, and syncs Coupa Supplier Information Management to S/4HANA Business Partner. Complements Coupa's standard S/4HANA integration for enterprise-specific custom fields, tolerance rules, and multi-plant routing.
Coupa-approved requisitions become S/4HANA POs with three-way match on invoice receipt and Supplier Information sync to Business Partner.
What this connector does
Coupa's enterprise spend-management platform is used at 3,000+ enterprises alongside S/4HANA landscapes; Coupa ships a standard S/4HANA integration but enterprises consistently need adapter work for custom fields, tolerance rules, and multi-plant / multi-purchasing-org routing. The ERPPlugs S/4HANA ↔ Coupa connector uses SAP IDoc + OData pathways (ORDERS05, INVOIC02, SupplierInvoiceOData) to bridge Coupa's Compass API into S/4HANA MM without touching the standard SAP integration. Coupa requisitions → S/4HANA POs with plant + purchasing group; Coupa invoices reconcile three-way against S/4HANA Goods Receipts; Coupa SIM profiles sync to Business Partner.
