## Short answer

SwiftScan RF Warehouse Mobile Buddy gives warehouse staff real-time barcode and QR scanning for EWM tasks on a mobile device. According to the SAP partner listing it integrates through OData APIs to S/4HANA and EWM. It is a lighter route than building custom RF screens.

## Erp

SAP S/4HANA

## Erp Key

## On Prem

true

## Product

SwiftScan RF Warehouse Mobile Buddy

## Vendor

Dragonfly Business Solutions

## Category

RF and barcode data collection

## Integration

**Method:** OData APIs to S/4HANA and EWM

**Detail:** The app calls OData services exposed by S/4HANA and EWM to fetch warehouse tasks and post confirmations. OData services need to be activated and secured on the SAP gateway, and your landscape determines which services are available.

**Method:** Mobile scanning client

**Detail:** Staff scan barcodes or QR codes with a handheld or phone, and the app validates scans against the open task before confirming. Check the supported devices, since camera scanning and dedicated scanners behave differently in noisy warehouses.

## Data Flows

**From:** EWM

**To:** SwiftScan RF

**Data:** Open warehouse tasks, bins, products, handling units

**Trigger:** Operator opens task list

**From:** SwiftScan RF

**To:** EWM

**Data:** Task confirmations, scanned handling units and quantities

**Trigger:** Operator scans and confirms

**From:** SwiftScan RF

**To:** S/4HANA

**Data:** Stock movement posting as a result of confirmed tasks

**Trigger:** Task confirmation

**From:** S/4HANA

**To:** SwiftScan RF

**Data:** Product master data for scan validation

**Trigger:** Lookup on scan

## Setup

### Confirm EWM scope

**Detail:** Check whether you run embedded EWM or decentralized EWM and which warehouse processes you need on mobile.

### Activate OData services

**Detail:** Enable and secure the required services on the SAP gateway and set up a technical or user-based authorization.

### Configure the app

**Detail:** Connect the app to the SAP system, set up warehouse numbers and map task types.

### Prepare labels

**Detail:** Make sure bin, handling unit and product labels are scannable with the formats the app expects.

### Test with real devices

**Detail:** Test in the warehouse itself, including Wi-Fi dead spots and lighting.

## Pitfalls

- Wi-Fi dead spots cause lost or duplicated scans if the app does not handle reconnects well.
- Barcode formats that differ from what the app expects (GS1-128 application identifiers, for example) cause rejected scans.
- OData authorization set too broad for the shop-floor user, or too narrow so tasks fail silently.
- Locked handling units or stock blocked in EWM show up as confusing errors on the device.

## Ai Layer

### Scan error explanations

**Description:** A private assistant reads EWM error messages and explains in plain language why a task failed and what the operator should do.

### Task backlog questions

**Description:** Ask which tasks have been open longest and by which bin or product, answered from EWM data on your own servers.

### Inventory difference triage

**Description:** Group count differences by bin and operator pattern and draft recount tasks for a supervisor to approve.

## Alternatives

- SAP's own EWM RF framework or Fiori warehouse apps may already cover your needs without a partner app.
- If you run classic WM or another warehouse system, a different RF product may fit better.

## Faq

### What does SwiftScan RF do?

**Answer:** It provides real-time barcode and QR scanning on mobile devices for EWM warehouse tasks, integrating with S/4HANA and EWM through OData APIs per its SAP partner listing.

### Does it work with on-prem S/4HANA?

**Answer:** OData is available in on-prem and cloud S/4HANA, but reachability depends on your gateway and network setup. Confirm the supported releases and deployment with the vendor.

### Where does AI fit in a warehouse?

**Answer:** As a read-only layer that explains errors, surfaces backlog and drafts recount or correction tasks. It runs on your infrastructure and a person approves any change to EWM.
