The vendor says it is SAP-certified for S/4HANA, SAP ECC 4.6c through 6.0 EHP8 and Business One 9.1, covering IM, WM and EWM, and that it works online or offline. The page focuses on S/4HANA, with ECC and Business One noted. ## Erp SAP S/4HANA ## Erp Key sap-s4hana ## On Prem true ## Product RFgen Mobile Edge for SAP ## Vendor RFgen Software ## Category RF and barcode data collection ## Integration **Method:** Vendor-stated SAP certification and real-time posting **Detail:** Per the vendor, handheld transactions are posted into SAP in real time using SAP standard interfaces, with coverage for Inventory Management, Warehouse Management and Extended Warehouse Management. The exact function modules and APIs depend on the module and release, so confirm with RFgen. **Method:** Offline mode **Detail:** Devices can keep working when Wi-Fi drops and synchronize when connectivity returns. Plan how queued transactions are validated on reconnect, because stock may have changed meanwhile. ## Data Flows **From:** RFgen device **To:** SAP IM/WM/EWM **Data:** Goods receipts against purchase orders and inbound deliveries **Trigger:** Operator scans PO or delivery and item **From:** SAP **To:** RFgen device **Data:** Pick lists, transfer orders, warehouse tasks **Trigger:** Delivery release or task creation **From:** RFgen device **To:** SAP **Data:** Pick confirmations and goods issues **Trigger:** Operator confirms pick **From:** RFgen device **To:** SAP **Data:** Physical inventory count results **Trigger:** Cycle count entered **From:** RFgen device **To:** SAP PP **Data:** Production confirmations and component issues **Trigger:** Operator reports order progress ## Setup ### Pick the SAP scenarios first **Detail:** List receiving, put-away, picking, counts and production reporting, and note whether you use IM, WM or EWM for each plant. ### Create the SAP connection user **Detail:** Use a dedicated user with narrow authorizations per scenario, and a separate user for test. ### Configure storage locations and bins **Detail:** Make sure storage locations, storage types and bins in SAP match what is physically labeled. ### Label and barcode readiness **Detail:** Check that materials, batches, locations and PO documents have scannable barcodes with consistent symbology. ### Select devices and test Wi-Fi coverage **Detail:** Walk the building with a test device and confirm coverage, or define offline behavior for dead zones. ### Run end-to-end tests with real transactions **Detail:** Post receipts, picks and counts in a quality system and compare stock and accounting documents. ### Pilot one area and train operators **Detail:** Start with one dock or zone and track rejected postings before wider rollout. ## Pitfalls - Batch and serial number handling set up differently in SAP than in the barcode, so scans fail on batch-managed items. - Unit of measure confusion between purchase, base and alternative units on the handheld. - Offline transactions posting against stock that changed, producing negative stock or rejected movements. - Storage location and bin master data not matching the physical bin labels. - Authorization gaps that only show up for specific plants or movement types in production. - Mixing IM and WM or EWM processes in one plant without a clear rule per material. ## Ai Layer ### Failed posting triage **Description:** A private assistant reads rejected mobile transactions and the matching SAP messages, explains the cause, such as a blocked batch or closed period, and drafts the corrective step for approval. ### Count variance analysis **Description:** Compare cycle count results with SAP book stock and recent movements to suggest likely causes before a count is posted. ### Plain-language stock questions **Description:** Let supervisors ask where a batch is or which receipts are unposted, answered from SAP data on your own infrastructure. ## Alternatives - SAP Fiori warehouse and inventory apps on rugged devices, if online-only scanning and SAP-native UI are enough. - SAP EWM RF framework for pure EWM sites, with SAP standard RF screens. - Other barcode and RF vendors, such as Cleverence or custom Zebra apps, where licensing or device mix favors them. ## Faq ### Which SAP versions does RFgen say it supports? **Answer:** RFgen states SAP certification for S/4HANA, SAP ECC from 4.6c to 6.0 EHP8, and SAP Business One 9.1, covering IM, WM and EWM. Verify the current certification list and your exact release with the vendor before purchase. ### Does it work without Wi-Fi? **Answer:** The vendor says the apps run online or offline. Offline transactions are queued and sent when the device reconnects, so you should define how conflicts, such as stock that moved in the meantime, are detected and reviewed. ### Does the mobile data stay on-prem? **Answer:** Mobile servers and SAP can both run in your own data center. A private AI assistant on your own GPUs can analyze rejected postings and counts without sending warehouse data to an outside service. ## Source https://www.rfgen.com/products/enterprise-mobility-solutions/sap-enterprise-mobility ## Search terms rfgen sap s/4hana mobile barcode, RFgen Mobile Edge SAP, SAP barcode scanning receiving picking, SAP IM WM EWM handheld, SAP Business One barcode RFgen, SAP ECC mobile warehouse app --- Talk to an engineer: https://netray.co/contact?intent=erp_ai | Machine catalog: https://netray.co/agent/catalog.json
