Why teams connect SAP S/4HANA and Scaleway Postgres

Give your engineers SAP S/4HANA's data in Scaleway Postgres: 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 Deliveries, Journal Entries, Customer / Supplier Roles, Production Orders from SAP S/4HANA into Scaleway Postgres 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 Scaleway Postgres sync back into SAP S/4HANA with its validations respected.

Common use cases

  • 01 Sync production tables from Scaleway Postgres into a CRM so sales and support see live product usage on customer records
  • 02 Run a two-way sync between Scaleway Postgres and SaaS tools so edits made in either system converge on the same rows
  • 03 Replicate material master and pricing data to e-commerce and quoting tools.
  • 04 Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.

Common sync patterns

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 Scaleway Postgres, 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 Scaleway Postgres for provisioning, access, and reporting systems that read from the database.

What you can sync between SAP S/4HANA and Scaleway Postgres

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.

SAP S/4HANA objects Scaleway Postgres objects How this pairing syncs
Deliveries Outbound delivery status synced to customer-facing systems for order tracking. Columns Postgres-native types, including JSONB and arrays, are mapped to fields in the paired system. Deliveries is specific to SAP S/4HANA and Columns to Scaleway Postgres — each maps to any object or custom field on the other side.
Journal Entries Financial postings read into warehouses and consolidation tools for reporting. Tables Primary sync unit; each table maps to an object or table on the other side of the sync. Journal Entries is specific to SAP S/4HANA and Tables to Scaleway Postgres — each maps to any object or custom field on the other side.
Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. Views Read-only sources for shaping data before it leaves the database. Customer / Supplier Roles is specific to SAP S/4HANA and Views to Scaleway Postgres — each maps to any object or custom field on the other side.
Production Orders Manufacturing order status surfaced in planning and operations tools. Materialized views Precomputed result sets that can be read on a schedule for downstream syncs. Production Orders is specific to SAP S/4HANA and Materialized views to Scaleway Postgres — each maps to any object or custom field on the other side.
Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs. Schemas Namespace tables so multiple applications or environments can be synced selectively. Business Partners is specific to SAP S/4HANA and Schemas to Scaleway Postgres — each maps to any object or custom field on the other side.
Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended. Sequences Generate primary keys; sync tooling must respect them when writing rows. Sales Orders is specific to SAP S/4HANA and Sequences to Scaleway Postgres — each maps to any object or custom field on the other side.

How changes propagate between SAP S/4HANA and Scaleway Postgres

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.

SAP S/4HANA Scaleway Postgres Interval-based propagation

DetectionStacksync polls SAP S/4HANA for changes on an incremental schedule, reading only records changed since the previous pass. Polling on change timestamps exposed by the OData services.

DeliveryEach detected change is applied to Scaleway Postgres as a row-level write, with types converted between the two schemas.

Scaleway Postgres SAP S/4HANA Sub-second propagation

DetectionChanges in Scaleway Postgres are captured at the source via change data capture — no polling loop against its API. Log-based CDC via PostgreSQL logical replication where the managed instance permits it.

DeliveryEach detected change is written to SAP S/4HANA through its API, with automatic retries and rate-limit backoff.

Rate-limit considerations

  • SAP S/4HANA: Subject to the platform's API rate limits, which vary by edition and communication arrangement.
  • Scaleway Postgres: Throughput is bounded by instance size and connection limits rather than API quotas.
