Why teams connect MySQL and SAP S/4HANA

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

Common use cases

  • Expose SaaS objects as MySQL tables so legacy internal tools built on MySQL can read live business data
  • Replicate ERP master data (customers, items, pricing) into the MySQL databases behind storefronts and portals
  • Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.

Controlled write-back

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

Read ERP records with a query

Records from SAP S/4HANA live in MySQL 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 S/4HANA interface, limits, and retries.

What you can sync between MySQL 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.

MySQL objects SAP S/4HANA objects
Databases (Schemas) Top-level namespaces that scope a sync's reads and writes. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Tables The primary sync target; rows map to records in connected systems. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
Views Read-side projections used as outbound sync sources. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
Columns Field-level mapping targets with engine-typed values. Billing Documents (Invoices) Invoice data pushed to CRMs and payment or collections tools for finance visibility.
Primary and Unique Keys Match keys for idempotent upserts and conflict handling. Deliveries Outbound delivery status synced to customer-facing systems for order tracking.
JSON Columns Validated semi-structured payloads for nested SaaS data. Journal Entries Financial postings read into warehouses and consolidation tools for reporting.

How the MySQL and SAP S/4HANA connectors work

MySQL

Integration surface
SQL wire protocol (MySQL client/server protocol)
Authentication
Database credentials entered as a connection string or parameters, with optional SSL root certificate upload and optional SSH tunnel (SSH user + SSH host)
Change detection
Database triggers — Stacksync creates deterministic triggers for internal logging and syncing (requires log_bin_trust_function_creators=ON when binary logging is enabled)
Capabilities
read · write · CDC
Rate limits
No API rate limits; throughput is bounded by connection limits and server resources
MySQL setup guide

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
