Why teams connect Oracle Fusion ERP and SAP

Two ERPs, one set of facts: Stacksync keeps Oracle Fusion ERP and SAP consistent in real time, whether they split the business or one is replacing the other.

Companies run two ERPs for structural reasons: a two-tier setup with subsidiaries on lighter systems, an acquisition that brought its own stack, a split by function or region, or a migration that will take quarters. In all of these, some of the same organizations, people, and transactions exist in both systems, and keeping them aligned by hand is a standing tax on the back office.

Stacksync syncs Payables Invoices, Receivables Invoices, Purchase Orders, Journal Entries in Oracle Fusion ERP with Inventory / Stock, Cost Centers, Business Partners, Materials (Products) in SAP bi-directionally and in real time, with field-level mapping across the two data models and conflict rules you define. A record changed in either system is reflected in the other within seconds, not at the next interface run.

Common use cases

  • 01 Create payables invoices in Fusion from AP capture or expense tools and sync approval and payment status back.
  • 02 Replicate GL balances and journals into a reporting database for consolidation across subsidiaries.
  • 03 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
  • 04 Publish plant-level inventory to e-commerce and planning systems on change or on schedule.

Common sync patterns

Shared master data

Where both systems keep records of the same customers, suppliers, or organizations, a correction in either updates the other.

Split by function

Where one system is the people or finance suite and the other runs operations, the records both sides depend on, such as organizations, cost centers, and reference data, stay in agreement.

Two-tier roll-up

Where subsidiaries run one system and headquarters runs the other, shared records and transactions flow up continuously, so consolidation starts from live data.

What you can sync between Oracle Fusion ERP and SAP

Representative objects on each side — any object or custom field can map to any target. Schemas are auto-detected; types are converted between the two systems.

Oracle Fusion ERP objects SAP objects How this pairing syncs
Purchase Orders Procurement documents exchanged with supplier portals and sourcing tools. Purchase Orders Procurement documents synced with supplier portals and spend tools. Same entity on both sides — records pair one-to-one and field-level changes reconcile in both directions.
Projects Project and task structures synced with delivery and time-tracking tools. Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals. Projects is specific to Oracle Fusion ERP and Outbound Deliveries to SAP — each maps to any object or custom field on the other side.
Fixed Assets Asset records reconciled with procurement and tracking systems. Billing Documents Invoices read for AR status and replicated for revenue reporting. Fixed Assets is specific to Oracle Fusion ERP and Billing Documents to SAP — each maps to any object or custom field on the other side.
Payments Disbursement records read to confirm settlement in upstream tools. GL Accounts and Journal Entries Financial postings replicated to warehouses for group finance analytics. Payments is specific to Oracle Fusion ERP and GL Accounts and Journal Entries to SAP — each maps to any object or custom field on the other side.
Suppliers Vendor master data synced with procurement and AP automation systems. Production Orders Manufacturing orders exchanged with MES and scheduling systems. Suppliers is specific to Oracle Fusion ERP and Production Orders to SAP — each maps to any object or custom field on the other side.
Customers Receivables customer records aligned with CRM accounts. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Customers is specific to Oracle Fusion ERP and Inventory / Stock to SAP — each maps to any object or custom field on the other side.

How changes propagate between Oracle Fusion ERP and SAP

Each direction of the sync is driven by what the source system can signal and what the destination accepts — detection, delivery, and expected latency below.

Oracle Fusion ERP SAP Interval-based propagation

DetectionStacksync polls Oracle Fusion ERP for changes on an incremental schedule, reading only records changed since the previous pass. Polling on last-updated attributes.

DeliveryEach detected change is written to SAP through its API, with automatic retries and rate-limit backoff.

SAP Oracle Fusion ERP Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

Rate-limit considerations

  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
