Why teams connect Couchbase and SAP

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

Common use cases

  • 01 Stream document mutations via DCP into downstream systems so caches, search indexes, or warehouses stay current.
  • 02 Two-way sync between Couchbase (serving application data) and a CRM so support and sales teams see live application state.
  • 03 Expose sales order and delivery status to customer portals through a synced Postgres database instead of direct SAP access.
  • 04 Publish plant-level inventory to e-commerce and planning systems on change or on schedule.

Common sync patterns

Read ERP records with a query

Records from SAP live in Couchbase 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 Couchbase, so jobs and triggers can respond as the business record changes.

What you can sync between Couchbase 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.

Couchbase objects SAP objects How this pairing syncs
Buckets Top-level data containers, roughly analogous to a database, that scope replication and memory quotas. Production Orders Manufacturing orders exchanged with MES and scheduling systems. Buckets is specific to Couchbase and Production Orders to SAP — each maps to any object or custom field on the other side.
Scopes Namespaces inside a bucket used to group collections, similar to schemas. Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Scopes is specific to Couchbase and Inventory / Stock to SAP — each maps to any object or custom field on the other side.
Collections Table-like groupings of documents that syncs typically map one-to-one to destination tables. Cost Centers Controlling masters read for mapping costs in finance integrations. Collections is specific to Couchbase and Cost Centers to SAP — each maps to any object or custom field on the other side.
JSON Documents The core records; schemaless JSON keyed by document id, flattened or mapped to relational rows in syncs. Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. JSON Documents is specific to Couchbase and Business Partners to SAP — each maps to any object or custom field on the other side.
Global Secondary Indexes Indexes that make SQL++ query-based extraction efficient. Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Global Secondary Indexes is specific to Couchbase and Materials (Products) to SAP — each maps to any object or custom field on the other side.
XDCR replications Cluster-to-cluster replication streams, useful context when choosing a sync source cluster. Sales Orders Order documents written from external channels and read for status and fulfillment. XDCR replications is specific to Couchbase and Sales Orders to SAP — each maps to any object or custom field on the other side.

How changes propagate between Couchbase and SAP

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.

Couchbase SAP Sub-second propagation

DetectionChanges in Couchbase are captured at the source via change data capture — no polling loop against its API. Database Change Protocol (DCP) streams document mutations.

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

SAP Couchbase 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 Couchbase as a row-level write, with types converted between the two schemas.

Rate-limit considerations

  • Couchbase: Throughput is bounded by cluster sizing rather than API rate limits.
  • SAP: Throttling is configured at the gateway and tenant level rather than as a single published rate limit.
