Why teams connect Citus and SAP S/4HANA

Give your engineers SAP S/4HANA's data in Citus: 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 Sales Orders, Purchase Orders, Products / Materials, Billing Documents (Invoices) from SAP S/4HANA into Citus 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 Citus sync back into SAP S/4HANA with its validations respected.

Common use cases

  • Write CRM or billing records into reference tables so distributed queries can join operational context locally on every node.
  • Use a Citus cluster as the scalable operational store behind a customer-facing app while syncing summaries back to internal tools.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.

React to ERP changes

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

Controlled write-back

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

What you can sync between Citus 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.

Citus objects SAP S/4HANA objects
Distributed tables Tables sharded across worker nodes by a distribution column; the main sync target for large datasets. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.
Reference tables Small lookup tables replicated to every node, synced like ordinary Postgres tables. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Local tables Coordinator-only tables that behave exactly like standard PostgreSQL tables. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
Schemas Standard Postgres namespaces used to scope what a sync user can read and write. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
Views Curated projections over distributed data, often used as read-only sync sources. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
Sequences Key generators that matter when external writes must not collide with application inserts. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.

How the Citus and SAP S/4HANA connectors work

Citus

Integration surface
PostgreSQL wire protocol; any standard Postgres driver connects to the coordinator node
Authentication
Database credentials (standard PostgreSQL authentication; managed deployments add cloud IAM options)
Change detection
PostgreSQL logical decoding / CDC, with caveats: changes to distributed tables occur on worker shards, so CDC setup differs from single-node Postgres
Capabilities
read · write · CDC

SAP S/4HANA

Integration surface
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
Change detection
Polling on change timestamps exposed by the OData services; business events can be emitted through SAP's event infrastructure on cloud editions
Capabilities

Rate limits
Subject to the platform's API rate limits, which vary by edition and communication arrangement
