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

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

Common use cases

  • Push billing or entitlement changes from finance tools into Spanner tables the application reads at runtime.
  • Use change streams to feed near-real-time copies of operational tables into an analytics warehouse.
  • Keep supplier records aligned between S/4HANA procurement and third-party spend platforms.
  • Push closed-won CRM opportunities into S/4HANA as sales orders without manual re-keying.

React to ERP changes

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

Where SAP S/4HANA is the HR system of record: people data for internal systems

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