Why teams connect Google Cloud SQL and SAP S/4HANA

Give your engineers SAP S/4HANA's data in Google Cloud SQL: 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 Google Cloud SQL 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 Google Cloud SQL sync back into SAP S/4HANA with its validations respected.

Common use cases

  • Keep an internal admin application backed by Cloud SQL consistent with an ERP or billing system.
  • Migrate from a self-managed database by syncing Cloud SQL and the legacy system during cutover.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.
  • Surface invoice and payment status from S/4HANA inside the CRM so account teams see open balances.

Read ERP records with a query

Records from SAP S/4HANA live in Google Cloud SQL 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.

React to ERP changes

Updates in SAP S/4HANA arrive as row changes in Google Cloud SQL, so jobs and triggers can respond as the business record changes.

What you can sync between Google Cloud SQL 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.

Google Cloud SQL objects SAP S/4HANA objects
Rows Read and written by primary key during each sync cycle. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types.
Views Read-only sources for shaping data before syncing it out. Production Orders Manufacturing order status surfaced in planning and operations tools.
Transaction logs MySQL binlog or PostgreSQL WAL, the source for log-based change capture. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.
Instances The managed MySQL, PostgreSQL, or SQL Server server a sync connects to. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Databases Scope the tables included in a sync configuration. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
Schemas Namespace tables in PostgreSQL and SQL Server instances. Products / Materials Material master data distributed to e-commerce, PIM, and CRM catalogs.
