Two-way sync
Changes in DuckDB or SAP S/4HANA instantly reflect in both systems. No stale data, no manual imports.
Keep DuckDB and SAP S/4HANA in sync without custom scripts. Cut weeks of integration work, eliminate silent data drift, and give your team a single, reliable source of truth.
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 DuckDB 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 DuckDB sync back into SAP S/4HANA with its validations respected.
Scripts and services read and write the synced tables; Stacksync handles the SAP S/4HANA interface, limits, and retries.
Updates in SAP S/4HANA arrive as row changes in DuckDB, so jobs and triggers can respond as the business record changes.
Worker and org records stay current in DuckDB for provisioning, access, and reporting systems that read from the database.
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.
| DuckDB objects | SAP S/4HANA objects | |
|---|---|---|
| Schemas Namespaces within a database used to organize tables in sync outputs. | Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs. | |
| Tables Columnar tables created via SQL; the destination for materialized sync data. | Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility. | |
| Views SQL views used to shape or filter data for downstream consumers. | Deliveries Outbound delivery status synced to customer-facing systems for order tracking. | |
| External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. | Journal Entries Financial postings read into warehouses and consolidation tools for reporting. | |
| Attached databases Additional database files or external systems attached into one session for cross-source queries. | Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types. | |
| Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. | Production Orders Manufacturing order status surfaced in planning and operations tools. |
Real-time sync, workflow automation, event queues, EDI, and monitoring, for every DuckDB–SAP S/4HANA connection.
Changes in DuckDB or SAP S/4HANA instantly reflect in both systems. No stale data, no manual imports.
Trigger automated workflows whenever DuckDB or SAP S/4HANA data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.
Handle millions of events per minute without losing a single DuckDB or SAP S/4HANA record.
Track your DuckDB ⇄ SAP S/4HANA sync health, view errors, and replay failed events in one click.
Transform legacy EDI complexity into simple database interactions between DuckDB and SAP S/4HANA.
Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.
Authenticate DuckDB and SAP S/4HANA with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.
Pick the DuckDB and SAP S/4HANA objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
Fields map automatically even when names and types differ. Stacksync handles transformation and type casting for you, zero configuration required.
Yes. Stacksync provides a managed, real-time two-way integration between DuckDB and SAP S/4HANA: authenticate both systems, choose the objects to sync (such as DuckDB's Schemas and Tables), map fields visually, and changes propagate both ways in milliseconds — no code required.
On the DuckDB side: Attached databases, Database files, Schemas, Tables, plus custom fields where DuckDB exposes them. On the SAP S/4HANA side: Purchase Orders, Products / Materials, Billing Documents (Invoices), Deliveries. Stacksync auto-detects both schemas and converts types between the two systems.
Yes. Each object mapping can be bidirectional or restricted to a single direction (both systems accept writes). Read-only mirrors, one-way pushes, and full two-way sync can be mixed in the same integration.
Common patterns for DuckDB and SAP S/4HANA: Internal tools and automations without API code; React to ERP changes; Where SAP S/4HANA is the HR system of record: people data for internal systems. Scripts and services read and write the synced tables; Stacksync handles the SAP S/4HANA interface, limits, and retries.
DuckDB: In-process SQL engine via client libraries (Python, Node.js, JDBC, CLI); no server or network API by default. Authentication: None built in; access control is file-system level (MotherDuck adds token auth for its hosted service). SAP S/4HANA: OData REST APIs (v2/v4), with SOAP, BAPI/RFC, and IDoc interfaces on on-premise editions. Authentication: OAuth 2.0 with communication arrangements on cloud editions; basic auth or certificate-based on-premise. Stacksync manages authentication, retries, and rate limits on both sides.
DuckDB: Execution is columnar and vectorized, optimized for analytical scans rather than high-frequency transactional writes. SAP S/4HANA: Cloud and on-premise editions expose different API allowlists, so field availability depends on the edition. Stacksync's field mapping accounts for these differences between DuckDB and SAP S/4HANA without custom code.
