Oracle Fusion Cloud ERP and JAGGAER integration

What moves between them

The main flow moves from Oracle Fusion into JAGGAER. Purchase orders, invoice headers, supplier master records, and GL account mappings are polled from Oracle Fusion and posted into JAGGAER's procurement system on a configurable schedule. Invoice receipt records and PO acknowledgments flow from JAGGAER back to Oracle Fusion for three-way matching. Reference data such as suppliers, accounts, and cost centers are aligned bidirectionally so procurement transactions land on valid GL dimensions in both systems.

How ml-connector handles it

ml-connector stores OAuth credentials for both systems encrypted and manages token refresh automatically when either system returns a 401 response. On the Oracle Fusion side, it polls the REST API using LastUpdateDate filters to retrieve only changed records since the last sync run. For JAGGAER, it uses the J1P endpoint paths provisioned during the customer's onboarding and handles the token endpoint at the customer-specific instance URL. GL accounts from Oracle Fusion are mapped to JAGGAER cost centers before posting any transaction, so invoice lines reference valid accounts. Because both systems use OAuth with time-limited tokens, ml-connector tracks expiry times and refreshes proactively to avoid mid-request failures. All pulled records carry a full audit trail and job ID so a failed downstream posting can be retried without duplication. When a supplier or account is updated in one system, ml-connector can align it in the other on the next poll cycle, keeping the two systems converged.

A real-world example

A large discrete manufacturer uses Oracle Fusion Cloud ERP for financials and procurement across multiple divisions and JAGGAER as the enterprise source-to-pay system to manage supplier contracts, auctions, and invoicing across all locations. Before the integration, the procurement team exported purchase orders from Oracle Fusion, re-entered them into JAGGAER by hand, then waited for supplier acknowledgments to come back through JAGGAER before manually matching them to invoices in Oracle Fusion's three-way matching process. This created delays in procurement cycles and frequent discrepancies between the two systems during month-end. With Oracle Fusion and JAGGAER connected, purchase orders flow automatically from the ERP into the supplier portal, supplier acknowledgments and invoice receipts come back into Oracle Fusion for matching, and supplier changes propagate instantly to both systems. Procurement cycles accelerate and the finance team eliminates manual re-keying in both directions.

What you can do

• •Sync Oracle Fusion purchase orders, invoices, and supplier master records to JAGGAER automatically on a schedule.
• •Map Oracle Fusion GL accounts and cost centers to JAGGAER procurement dimensions so transactions post to the correct accounts.
• •Authenticate both systems independently using their respective OAuth 2.0 flows and manage token expiry transparently.
• •Receive invoice receipts and PO acknowledgments from JAGGAER back into Oracle Fusion for three-way matching and settlement.
• •Track every record with a full audit trail and enable replay of failed syncs without duplicate postings.

Questions

Which direction does data move between Oracle Fusion and JAGGAER?

The main flow is from Oracle Fusion into JAGGAER: purchase orders, invoices, and supplier records sync automatically to the procurement system. PO acknowledgments and invoice receipts come back from JAGGAER into Oracle Fusion for three-way matching. Supplier and GL account reference data can be aligned bidirectionally so both systems converge.

How does ml-connector handle the different OAuth setups for each system?

ml-connector stores credentials for both the OCI Identity Domain (Oracle Fusion) and the J1P auth endpoint (JAGGAER) encrypted in the database. It refreshes tokens independently when either system returns a 401, and tracks token expiry times to refresh proactively before they expire. This keeps both API connections alive without interruption.

Does the integration require JAGGAER professional services setup?

J1P REST endpoint paths are provided by JAGGAER during customer onboarding, so ml-connector uses the paths your JAGGAER team has already configured. Event-driven sync from JAGGAER requires JAGGAER professional services, but the standard poll-only integration via J1P REST works with credentials alone once onboarding is complete.
