Why teams connect SAP and SQL Server

Give your engineers SAP's data in SQL Server: 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 Purchase Orders, Outbound Deliveries, Billing Documents, GL Accounts and Journal Entries from SAP into SQL Server 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 SQL Server sync back into SAP with its validations respected.

Common use cases

  • Feed a cloud warehouse from SQL Server continuously using native CDC instead of SSIS batch jobs
  • Consolidate branch or plant databases into a single operational SQL Server hub
  • Replicate journal entries and billing documents to a warehouse for finance analytics without loading the ERP.
  • Keep MES and WMS systems aligned with production orders and goods movements.

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 SQL Server, 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 SQL Server for provisioning, access, and reporting systems that read from the database.

What you can sync between SAP and SQL Server

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 SQL Server objects
Inventory / Stock Plant and storage-location quantities synced to storefronts and planning tools. Tables The primary sync target; rows map to records in connected systems.
Cost Centers Controlling masters read for mapping costs in finance integrations. Views Read-side projections used as outbound sync sources.
Business Partners The unified customer and supplier master in S/4HANA, the anchor object for CRM and procurement syncs. Columns Field-level mapping targets with T-SQL types.
Materials (Products) Item master with plant and sales views, synced to commerce, PLM, and CRM systems. Primary and Unique Keys Match keys for idempotent upserts and conflict handling.
Sales Orders Order documents written from external channels and read for status and fulfillment. CDC Change Tables System-populated tables holding captured inserts, updates, and deletes for consumers.
Purchase Orders Procurement documents synced with supplier portals and spend tools. Stored Procedures T-SQL logic that can validate or post-process synced rows.
What ships with SAP ⇄ SQL Server

Trigger automated workflows whenever SAP or SQL Server data changes, update records, fire webhooks, or kick off sequences without brittle API scripts.

At scale

Event queues

Handle millions of events per minute without losing a single SAP or SQL Server record.

Observability

Monitoring

Track your SAP ⇄ SQL Server sync health, view errors, and replay failed events in one click.

Trading partners

EDI

Transform legacy EDI complexity into simple database interactions between SAP and SQL Server.

How the SAP and SQL Server connectors work

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

SQL Server

Integration surface
SQL over the TDS wire protocol (Tabular Data Stream), via ODBC/JDBC/ADO.NET drivers
Authentication
Database credentials entered as a connection string or as parameters (host/user/password) in the Create New Sync page
Change detection
SQL Server Native Change Data Capture (CDC); a DBA runs a one-time setup script with sysadmin privileges to enable CDC and create Stacksync wrapper procedures
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput depends on instance resources, licensing tier, and connection limits

How it works

How to connect SAP to SQL Server — three steps, no code

Configure and sync within minutes, no code. Whether you sync 50k or 100M+ records, Stacksync handles the queues, infra, and plumbing. Integrations are non-invasive and need zero setup on your systems.

  1. 01

    Connect your apps

    Authenticate SAP and SQL Server with each platform's native method — OAuth, API keys, or service accounts — plus secure options like SSH tunneling, IP whitelisting, and VPC peering.

    Choose tables

    Pick the SAP and SQL Server objects to sync — Stacksync auto-detects both schemas, including custom fields where the platform exposes them. Sync to existing tables, or let Stacksync create new ones with ideal data types.
