Why teams connect AWS Aurora PostgreSQL and SAP S/4HANA

Give your engineers SAP S/4HANA's data in AWS Aurora PostgreSQL: 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 Billing Documents (Invoices), Deliveries, Journal Entries, Customer / Supplier Roles from SAP S/4HANA into AWS Aurora PostgreSQL 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 AWS Aurora PostgreSQL sync back into SAP S/4HANA with its validations respected.

Common use cases

  • Keep a customer-facing Aurora database aligned with an internal admin tool, with writes accepted on both sides.
  • Feed operational dashboards from a read replica while the writer handles sync traffic.
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

React to ERP changes

Updates in SAP S/4HANA arrive as row changes in AWS Aurora PostgreSQL, 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 AWS Aurora PostgreSQL for provisioning, access, and reporting systems that read from the database.

Controlled write-back

Choose exactly which tables and fields may flow from AWS Aurora PostgreSQL back into SAP S/4HANA, keeping the ERP authoritative.

What you can sync between AWS Aurora PostgreSQL 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.

AWS Aurora PostgreSQL objects SAP S/4HANA objects
Tables The core sync unit; rows are matched across systems by primary key. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.
Rows Inserted, updated, and deleted in both directions during bi-directional syncs. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Columns Rich Postgres types including JSONB and arrays are mapped to the paired system's fields. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
Primary keys and constraints Identify rows for upserts and enforce integrity on sync writes. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
Views and materialized views Usable as read-only sources for filtered or precomputed sync datasets. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
Foreign keys Relationship metadata that syncs can translate into object references elsewhere. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
