Commerce and ERP telling the same story.
Pricing, orders, customers, stock and invoices kept consistent across SAP Commerce, S/4HANA and the wider enterprise landscape.
Symptoms of weak ERP integration
The storefront quotes prices or availability the ERP later contradicts. Orders need manual re-entry, or fail without anyone noticing. Credit blocks appear at the wrong moment in the buying journey. Customer service spends its day answering questions the ERP could answer directly.
What the integration covers
Order flow: Order creation, confirmation, changes, cancellation and returns with status kept in sync. Pricing & conditions: Contract, list and volume pricing retrieved with defined caching and fallback rules. Availability & delivery dates: Stock views and promised dates with tolerances the business has agreed. Customer & credit: Account master data, credit status and payment terms reflected in the buying journey. Invoices & documents: Invoices, delivery notes and documents retrieved on demand for self-service. Recovery & monitoring: Retries, reconciliation and alerting so failures are visible and recoverable.
How we build it
SAP Integration Suite / CPI: iFlows, mappings and protocol handling with transportable configuration. OData & IDoc / BAPI: The right interface for each flow rather than one pattern applied everywhere. Synchronous vs asynchronous: A deliberate decision per flow, based on what the customer journey can tolerate. Caching strategy: Explicit freshness rules so speed never silently costs accuracy. Idempotency: Safe retries with no duplicate orders or double postings. Observability: Flow-level dashboards and alerts your operations team can act on.
How we approach ERP integration
Agree the system of record for each data domain, explicitly and in writing. Define interface contracts and error semantics before development. Build the highest-risk flow first — usually order submission. Test against production-like data volumes and known edge cases. Instrument everything, then hand over runbooks with the code.
ERP integration questions
Do you integrate with S/4HANA and ECC? Yes, both. The integration patterns differ in detail — available APIs, OData services, IDoc and BAPI usage — but the architectural discipline is the same. Should pricing be real time or cached? It depends on the price complexity and the journey. We define freshness requirements per scenario and design caching and fallback so speed never silently costs accuracy. What happens if the ERP is unavailable? Flows are designed with explicit degradation: what the storefront shows, what it queues, and what it refuses to promise. That behaviour is agreed with the business rather than left to chance. Can you work with our existing middleware? Yes. We use SAP Integration Suite when it fits the landscape, and work with your existing middleware or API gateway when that is what you operate.
