Why teams connect OpenSearch and SAP

Give your engineers SAP's data in OpenSearch: 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 Production Orders, Inventory / Stock, Cost Centers, Business Partners from SAP into OpenSearch 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 OpenSearch sync back into SAP with its validations respected.

Common use cases

  • Sync product catalogs from an ERP or database into the indexes that back storefront search.
  • Keep Postgres as the source of truth while mirroring rows to OpenSearch for full-text and vector queries.
  • Keep MES and WMS systems aligned with production orders and goods movements.
  • Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.

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

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

Controlled write-back

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

Read ERP records with a query

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

What you can sync between OpenSearch 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.

OpenSearch objects SAP objects
Snapshots Backup artifacts, relevant when reseeding an index from a repository Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs.
Indexes The core container; synced records land in indexes with defined mappings Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems.
Documents JSON records written via the index and bulk APIs and read via search queries Sales Orders Order documents written from external channels and read for status and fulfillment.
Index aliases Stable names over rotating indexes, used for zero-downtime reindex during backfills Purchase Orders Procurement documents synced with supplier portals and spend tools.
Index templates Mapping and settings presets applied to new indexes a sync creates Outbound Deliveries Shipment documents synced to WMS, carriers, and customer portals.
Ingest pipelines Server-side processors that transform documents as they are written Billing Documents Invoices read for AR status and replicated for revenue reporting.

How the OpenSearch and SAP connectors work

OpenSearch

Integration surface
REST API over HTTP(S) with JSON payloads
Authentication
basic authentication with the security plugin, or AWS IAM request signing on Amazon OpenSearch Service
Change detection
no native change feed; reads rely on queries with scroll or point-in-time polling
Capabilities
read · write
Rate limits
throughput bounded by cluster sizing rather than fixed API quotas

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
