Why teams connect SAP and SAP Hana

Give your engineers SAP's data in SAP Hana: 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 Materials (Products), Sales Orders, Purchase Orders, Outbound Deliveries from SAP into SAP Hana 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 SAP Hana sync back into SAP with its validations respected.

Common use cases

  • 01 Read SYS.TABLES and TABLE_COLUMNS system views to auto-discover schema and generate field mappings when new tables are added to the sync.
  • 02 Detect inserts, updates, and deletes on high-write tables via AFTER triggers or a last-modified column and replicate the deltas downstream near-real-time.
  • 03 Keep MES and WMS systems aligned with production orders and goods movements.
  • 04 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.

Common sync patterns

Read ERP records with a query

Records from SAP live in SAP Hana as ordinary tables or collections, joinable with the rest of your data.

Internal tools and automations without API code

Scripts and services read and write the synced tables; Stacksync handles the SAP interface, limits, and retries.

React to ERP changes

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

What you can sync between SAP and SAP Hana

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 objects SAP Hana objects How this pairing syncs
Production Orders Manufacturing orders exchanged with MES and scheduling systems. Calculation views Modeled analytic views over base tables; read-only sources for pushing aggregated or joined results into a warehouse or downstream app. Production Orders is specific to SAP and Calculation views to SAP Hana — each maps to any object or custom field on the other side.
Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. SQL views Standard database views; read-only projections synced outbound when the source data should not be exposed as raw base tables. Inventory / Stock is specific to SAP and SQL views to SAP Hana — each maps to any object or custom field on the other side.
Cost Centers Controlling masters read for mapping costs in finance integrations. Schemas Namespaces that group tables and views; the connector targets a schema and enumerates its objects from the catalog to build the sync. Cost Centers is specific to SAP and Schemas to SAP Hana — each maps to any object or custom field on the other side.
Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. Sequences Server-generated key values; relevant when writing rows into tables whose identity is assigned HANA-side rather than by the source system. Business Partners is specific to SAP and Sequences to SAP Hana — each maps to any object or custom field on the other side.
Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Triggers AFTER INSERT/UPDATE/DELETE triggers capture changes into a shadow/logging table so updates and deletes are detected near-real-time without full scans. Materials (Products) is specific to SAP and Triggers to SAP Hana — each maps to any object or custom field on the other side.
Sales Orders Order documents written from external channels and read for status and fulfillment. System-versioned temporal tables Column store tables with a history table tracking each row's validity period; used to reconstruct update and delete history for change capture. Sales Orders is specific to SAP and System-versioned temporal tables to SAP Hana — each maps to any object or custom field on the other side.

How changes propagate between SAP and SAP Hana

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 SAP Hana Sub-second propagation

DetectionSAP notifies Stacksync of record changes through webhook events. Business events via SAP Event Mesh on S/4HANA.

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

SAP Hana SAP Sub-second propagation

DetectionChanges in SAP Hana are captured at the source via change data capture — no polling loop against its API. Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table.

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

Rate-limit considerations

  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
  • SAP Hana: No SaaS-style request quota; throughput is bounded by connection limits, statement memory caps, and workload-class admission control (concurrency/memory limits) that share capacity with production queries.

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

SAP Hana

Integration surface
SQL over the SAP HANA client (JDBC/ODBC drivers); OData/REST via XS for app-layer access
Authentication
Dedicated database user credentials over an encrypted TLS connection (password sent hashed); Kerberos, SAML, JWT, and X.509 certificate authentication are also supported. SAP HANA Cloud enforces TLS and IP allowlisting.
Change detection
Polling on a last-modified timestamp column, or AFTER INSERT/UPDATE/DELETE triggers writing to a shadow table; system-versioned temporal tables and SLT/SDI provide trigger- and log-based CDC. No native webhooks.
