Why teams connect Oracle DB and SAP S/4HANA

Give your engineers SAP S/4HANA's data in Oracle DB: read it with normal queries, write back through the sync, and skip the ERP API entirely.

ERP data sits behind interfaces built for the ERP's own modules, not for your internal systems. Teams that need those records, for reporting services, internal tools, or automations, end up writing integration code against a strict API and maintaining it through every upgrade.

Stacksync mirrors Purchase Orders, Products / Materials, Billing Documents (Invoices), Deliveries from SAP S/4HANA into Oracle DB and keeps both sides consistent in real time. Whatever SAP S/4HANA is the system of record for, whether financials, operations, people, or procurement, those records become rows your code can query, and changes written in Oracle DB sync back into SAP S/4HANA with its validations respected.

Common use cases

  • Expose a curated subset of an on-prem Oracle ERP schema to cloud tools by syncing it to a managed Postgres.
  • Keep legacy Oracle applications running while newer services read and write the same data through a synced copy.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.
  • Replicate material master and pricing data to e-commerce and quoting tools.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the SAP S/4HANA interface, limits, and retries.

React to ERP changes

Updates in SAP S/4HANA arrive as row changes in Oracle DB, so jobs and triggers can respond as the business record changes.

Where SAP S/4HANA is the HR system of record: people data for internal systems

Worker and org records stay current in Oracle DB for provisioning, access, and reporting systems that read from the database.

What you can sync between Oracle DB and SAP S/4HANA

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 DB objects SAP S/4HANA objects
PL/SQL procedures and packages In-database logic that can consume or transform synced data Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
Partitions Physical subdivisions relevant when replicating high-volume tables Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
JSON columns Document data stored in the converged engine and synced alongside relational rows Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
Tables The primary read/write surface for row-level sync over SQL Journal Entries Financial postings read into warehouses and consolidation tools for reporting.
Views Curated read-only projections exposed to downstream consumers Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types.
Materialized views Precomputed results occasionally used as stable replication sources Production Orders Manufacturing order status surfaced in planning and operations tools.
