## Short answer

Casset Tagging Inventory RFID from Crave InfoTech is listed on SAP's partner pages for S/4HANA and S/4HANA Cloud Public Edition. It uses RFID tags on inbound and outbound processes and supports bulk scanning for cycle counts. The listing sits under SAP's technology platform (BTP) partner pages.

## Product

Casset Tagging Inventory RFID

## Vendor

Crave InfoTech

## Category

RFID and cycle counting

## Integration

**Method:** SAP partner solution on BTP

**Detail:** The listing places the product under SAP's technology platform partners, which suggests a BTP-based application talking to S/4HANA. The listing does not publish the exact APIs, so confirm with Crave InfoTech whether it uses OData services, BAPIs or other interfaces for your release.

**Method:** RFID reader layer

**Detail:** Fixed portals and handheld readers capture tag reads. The application turns those into goods movements or inventory count entries in S/4HANA through the partner's integration.

## Data Flows

**From:** S/4HANA

**To:** Casset

**Data:** Material master, storage locations, batch data and open inbound or outbound documents

**Trigger:** Sync or document selection

**From:** RFID readers

**To:** Casset

**Data:** Tag IDs, read counts, location of scan

**Trigger:** Receiving, shipping or cycle count scan

**From:** Casset

**To:** S/4HANA

**Data:** Goods movements or physical inventory counts

**Trigger:** Scan confirmation or count completion

**From:** S/4HANA

**To:** Casset

**Data:** Posted document numbers and count differences

**Trigger:** After posting

## Setup

### Define the use case

**Detail:** Choose between tagging at receiving, shipping verification and cycle counts, and identify the storage areas where RFID reads are reliable.

### Run a reader site survey

**Detail:** Metal racks, liquids and dense packaging affect RFID reads, so test tag types and reader placement on real stock.

### Decide tag encoding

**Detail:** Choose whether tags carry a serial number, a material and batch, or an ID that maps to an SAP object, and keep it consistent.

### Connect to S/4HANA

**Detail:** Configure the integration with a technical user restricted to the relevant movement types and physical inventory functions.

### Pilot a cycle count

**Detail:** Count one zone with RFID and with a manual count and compare differences.

### Set difference handling

**Detail:** Define tolerances, recount rules and who approves a posting of differences.

## Pitfalls

- RFID read shadowing in metal racks, which undercounts stock and causes false differences.
- Tags reused or removed when items are repacked, breaking the link to the SAP material or batch.
- Batch and storage location mismatches between the tag and the S/4HANA record.
- Posting count differences automatically without review, which writes bad data into inventory valuation.
- Duplicate reads from overlapping readers or repeated passes, inflating counts.

## Ai Layer

### Count difference triage

**Description:** Read RFID scans and S/4HANA book stock to group differences by likely cause such as read shadowing, a recent transfer not yet posted or a mis-tagged batch, and draft recount lists.

### Plain-language inventory questions

**Description:** Let a stores supervisor ask which locations have the largest unresolved differences this month and see the supporting records.

### Tag lifecycle checks

**Description:** Flag tags with no movement for long periods, or tags linked to materials that have changed status, for a person to review.

## Alternatives

- Barcode scanning with S/4HANA's standard physical inventory process is often enough when stock is easy to scan line by line.
- SAP Extended Warehouse Management with RF devices if you need a full warehouse process rather than counting alone.
- A different RFID vendor or a SAP Auto-ID approach if your tag standards are already chosen.

## Faq

### Does RFID replace barcode scanning?

**Answer:** Not always. RFID is strong for fast bulk reads such as cycle counts and portal checks. Barcodes remain cheaper and more predictable for many items. Many sites use both, and the choice depends on materials, packaging and tag cost.

### How does the product connect to S/4HANA?

**Answer:** It is listed as a partner solution under SAP's BTP partner pages. The page does not specify the APIs, so ask Crave InfoTech which interfaces are used and whether they apply to your S/4HANA release.

### Can counts post to SAP automatically?

**Answer:** Technically that can be configured, but good practice is to review differences first. Posting differences changes inventory quantity and value, so set tolerances and require approval above them.

### How would a private AI layer help?

**Answer:** It can compare RFID reads with SAP stock, explain likely causes of differences and draft recount lists. It stays read-only, and a warehouse owner approves any posting.
