# SAP Commerce Cloud B2B with SAP S/4HANA: webshop to ERP integration > Source: https://netray.co/stack/sap-commerce-cloud-b2b-sap-s4hana > Publisher: Netray (netray.co), AI and integration engineering for ERP and manufacturing systems. > Section: ERP Stack ## Short answer SAP Commerce Cloud B2B is SAP's own webshop. Business partner and material data from S/4HANA feed the storefront, and web orders flow back to S/4HANA for fulfillment. The first-party integration runs through SAP Integration Suite, and it applies to S/4HANA Cloud and S/4HANA, so an on-premise ERP can sit behind a cloud storefront. ## Erp SAP S/4HANA ## Erp Key sap-s4hana ## On Prem true ## Product SAP Commerce Cloud (B2B) ## Vendor SAP ## Category B2B e-commerce ## Integration **Method:** SAP Integration Suite (first-party integration) **Detail:** SAP Integration Suite carries the messages between Commerce Cloud and S/4HANA. Master data replication goes from the ERP toward the storefront, and order creation goes the other way. SAP documents this in its learning journey on the Commerce Cloud and S/4HANA Cloud integration; for an on-premise S/4HANA you also need a secure connection into your network, commonly through SAP Cloud Connector. **Method:** Real-time ERP calls for price and stock **Detail:** B2B stores often need contract prices and availability from the ERP rather than a copy. Plan which values are replicated and which are fetched on demand, because that choice drives storefront speed and ERP load. ## Data Flows **From:** S/4HANA business partner **To:** Commerce Cloud **Data:** B2B customers, units, contacts and sold-to / ship-to relations **Trigger:** Initial load, then change replication **From:** S/4HANA material master **To:** Commerce Cloud **Data:** Products, descriptions, units of measure, classification **Trigger:** Initial load, then change replication **From:** S/4HANA pricing **To:** Commerce Cloud **Data:** List and customer-specific prices **Trigger:** Replication or on-demand call at browse and checkout **From:** Commerce Cloud **To:** S/4HANA sales order **Data:** Order header, items, ship-to, requested date **Trigger:** Customer places the order **From:** S/4HANA **To:** Commerce Cloud **Data:** Order status, delivery and invoice status **Trigger:** Status change in ERP ## Setup ### Decide the data ownership model **Detail:** Choose what the ERP owns (customers, materials, prices, stock) and what lives only in the storefront (content, images, marketing text). ### Provision Integration Suite **Detail:** Set up SAP Integration Suite and the integration content for Commerce Cloud and S/4HANA, with connectivity to the ERP. ### Connect on-premise S/4HANA **Detail:** Establish the secure tunnel, typically SAP Cloud Connector, and expose only the required services. ### Load business partners and materials **Detail:** Run the initial replication, then verify B2B units, account hierarchies and product catalogs. ### Configure pricing and availability **Detail:** Decide between replicated prices and live ERP pricing, and set caching rules for each. ### Map order creation **Detail:** Define sales organization, distribution channel, division, order type and partner functions used for web orders. ### Test the full order cycle **Detail:** Place orders with different customers, units of measure and partial stock, and follow them to delivery and invoice. ### Plan error handling **Detail:** Set alerts for failed replications and orders that did not reach the ERP, with an owner for each. ## Pitfalls - Customer hierarchies in SAP not matching the B2B unit structure, so users see the wrong accounts. - Unit of measure conversions differing between the webshop and the material master. - Replicated prices going stale when condition records change, leaving quotes that disagree with invoices. - Web orders failing on a blocked customer, missing incompleteness fields or credit block, with no one notified. - Stock shown from a single plant when fulfillment draws from several. - Cloud-to-on-premise connectivity breaking after network or certificate changes. ## Ai Layer ### Failed order triage **Description:** A private assistant reading the integration monitor and S/4HANA sales documents can explain why a web order stopped (credit block, missing partner, incompleteness) and suggest the fix for a person to apply. ### Price mismatch investigation **Description:** Compare the price shown on the storefront with the condition records used in the ERP and point at the record that differs. ### Customer self-service answers **Description:** Let customer service ask in plain language where an order is, reading order, delivery and invoice status from S/4HANA without opening several screens. ## Alternatives - A non-SAP B2B storefront on a headless commerce platform, if your catalog and content needs are unusual. - Customer portals using SAP Fiori apps directly for a small, known customer base. - EDI for large repeat customers, which skips the webshop and keeps order entry machine to machine. ## Faq ### Does Commerce Cloud B2B work with on-premise S/4HANA? **Answer:** SAP documents the integration for S/4HANA Cloud and S/4HANA through SAP Integration Suite. For an on-premise system you need a secure path from the cloud into your network, commonly SAP Cloud Connector. Confirm supported releases in SAP documentation. ### Which system owns prices? **Answer:** Normally the ERP does. You decide whether to replicate prices to the storefront or fetch them live from S/4HANA, trading speed against accuracy. Customer-specific pricing usually pushes teams toward live or frequently refreshed values. ### Can orders be edited after submission? **Answer:** Once an order exists in S/4HANA, changes are made in the ERP, and the storefront reflects status. How much editing customers can do online is a design decision for the project. ## Source https://learning.sap.com/learning-journeys/discover-the-foundations-of-sap-commerce-cloud-and-sap-s-4hana-cloud-integration/evaluating-the-integration-process_a0298760-4b20-45db-8ce5-c0c9384d079b ## Search terms sap commerce cloud s/4hana b2b integration, sap commerce cloud b2b, sap integration suite commerce cloud, sap b2b webshop s/4hana, sap commerce cloud order replication, hybris s/4hana --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
