Why teams connect DuckDB and SAP

Give your engineers SAP's data in DuckDB: 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 Outbound Deliveries, Billing Documents, GL Accounts and Journal Entries, Production Orders from SAP into DuckDB and keeps both sides consistent in real time. Whatever SAP 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 with its validations respected.

Common use cases

  • Use DuckDB as a transform step: read synced Parquet exports, aggregate with SQL, and write results back to an operational database.
  • Sync SaaS data to Parquet on object storage and query it with DuckDB without standing up a warehouse.
  • Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
  • Publish plant-level inventory to e-commerce and planning systems on change or on schedule.

React to ERP changes

Updates in SAP arrive as row changes in DuckDB, so jobs and triggers can respond as the business record changes.

Where SAP is the HR system of record: people data for internal systems

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

Controlled write-back

Choose exactly which tables and fields may flow from DuckDB back into SAP, keeping the ERP authoritative.

What you can sync between DuckDB 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.

DuckDB objects SAP objects
Tables Columnar tables created via SQL; the destination for materialized sync data. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools.
Views SQL views used to shape or filter data for downstream consumers. Cost Centers Controlling masters read for mapping costs in finance integrations.
External files (Parquet/CSV/JSON) Files DuckDB queries in place without loading, common as a sync interchange format. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs.
Attached databases Additional database files or external systems attached into one session for cross-source queries. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems.
Database files Single-file .duckdb databases that jobs read and write directly on disk or object storage. Sales Orders Order documents written from external channels and read for status and fulfillment.
Schemas Namespaces within a database used to organize tables in sync outputs. Purchase Orders Procurement documents synced with supplier portals and spend tools.

How the DuckDB and SAP connectors work

DuckDB

Integration surface
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)
Change detection
Polling or full re-reads; no change feed or transaction log API
Capabilities
read · write
Rate limits
No API rate limits; throughput is bounded by local compute and I/O

SAP

Integration surface
OData (v2/v4) APIs on S/4HANA; BAPI/RFC and IDoc on ECC and on-prem systems; SOAP services
Authentication
OAuth 2.0 or basic auth via communication arrangements on cloud editions; SAP user credentials for RFC on-prem
Change detection
Business events via SAP Event Mesh on S/4HANA; change pointers with IDocs or timestamp polling on ECC
Capabilities
read · write · webhooks
Rate limits
Throttling is configured at the gateway and tenant level rather than as a single published rate limit
