Why teams connect Google AlloyDB and SAP S/4HANA

Give your engineers SAP S/4HANA's data in Google AlloyDB: 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, Sales Orders, Purchase Orders, Products / Materials from SAP S/4HANA into Google AlloyDB 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 AlloyDB sync back into SAP S/4HANA with its validations respected.

Common use cases

  • Use logical replication to feed AlloyDB changes into warehouses or event pipelines without batch jobs.
  • Consolidate SaaS data into AlloyDB and serve analytics from its columnar engine without a separate OLAP store.
  • Replicate material master and pricing data to e-commerce and quoting tools.
  • Feed S/4HANA financial and logistics documents into a data warehouse for reporting without custom ABAP extracts.

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

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

Controlled write-back

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

Read ERP records with a query

Records from SAP S/4HANA live in Google AlloyDB as ordinary tables or collections, joinable with the rest of your data.

What you can sync between Google AlloyDB 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 AlloyDB objects SAP S/4HANA objects
Indexes Keep sync key lookups fast on high-volume tables. Journal Entries Financial postings read into warehouses and consolidation tools for reporting.
Sequences ID generation relevant when external systems insert rows. Customer / Supplier Roles Role-specific views of Business Partners mapped to CRM account types.
Replication Slots Logical replication artifacts that back log-based change capture. Production Orders Manufacturing order status surfaced in planning and operations tools.
Databases Standard PostgreSQL databases within an AlloyDB cluster that syncs connect to. Business Partners Unified customer and supplier master records, the anchor entity for CRM-to-ERP account syncs.
Schemas Namespaces used to separate synced SaaS data from application tables. Sales Orders Order headers and line items synced to CRMs and fulfillment systems as they are created or amended.
Tables Primary read/write target for bi-directional sync with CRMs and other systems. Purchase Orders Procurement documents shared with supplier portals and spend-management tools.
