Purpose

Currently, the work process in the warehouse is characterized by speed, reliability, and precision in processing individual goods movements. To make sure that work is performed efficiently and at a reasonable cost, the warehouse staff requires simple and easy-to-view control of each individual process. The radio frequency (RF) solution provides fast and error-free data communication through the use of mobile RF terminals. This, in turn, provides a high standard of quality.

The RF terminals receive data directly from the SAP System and transmit the results back to the system. You can scan the information that needs to be recorded, such as handling unit (HU) numbers, using a bar code (for example, based on UCC/EAN128 standards), and also scan the bar code to verify the storage bins.

The display of information on the RF terminal is possible with a graphical user interface. You can execute the individual functions using pushbuttons on a touch screen. If you are using a character-based device, SAP provides a special, non-graphic user interface.

Since the RF solution is an integral part of the standard SAP System, you can access the RF transactions either directly through the SAP menu or from mobile data-entry devices. Generated information is immediately available to the RF user and transmitted back to the SAP database instantly.

Integration

Mobile Data Entry is integrated with SAP’s Warehouse Management System (WMS) and Structure linkTask and Resource Management (TRM).

Warehouse Management System (WMS)

The RF solution supports the movement of goods in both HU-managed and non HU-managed storage locations.

·        In HU-managed storage locations, the RF solution supports the movement of goods through the specification of the respective handling units.

·        In non HU-managed storage locations, you can work with handling units as up to now in the delivery and in the shipment.

For more information, see Structure linkHandling Unit Management.

Task and Resource Management (TRM)

TRM  itself supports the customization of data presentation on RF devices. As part of this customization, you can include Mobile Data Entry menus and functions. For more information, see Structure linkPresentation Management in the SAP Library for Task and Resource Management.

Features

Mobile Data Entry provides a number of features, including the following:

GUI and Character Device Support

Mobile Data Entry supports both GUI and character-based devices. For more information, see RF Device Support.

Bar Code Support

Mobile Data Entry supports the use of bar codes for identification and verification purposes. For more information, see Bar Code Support.

RF Support of Warehouse Management Processes

Mobile Data Entry supports a wide variety of warehouse processes, including:

·        Goods receipts and issues

·        Picking

·        Putaway

·        Interleaving

·        Inventory counting

·        Loading and unloading

The RF solution guides the user through each activity that is executed in the warehouse. Limited information is displayed to the users, which they must then verify by scanning bar codes. For more information, see RF-Supported Warehouse Processes.

RF Activity Control

Mobile Data Entry supports the assignment of transfer orders to queues, according to physical areas of the warehouse and activities. The TOs can then be processed by users assigned to those queues.

The warehouse manager can utilize the RF Monitor, which operates as a central coordination point to ensure that the processing of transfer orders runs as efficiently as possible. For more information, see RF Queue Management.

Flexible RF Customizing

In Customizing for Mobile Data Entry, you can define the following:

·        The size and number of screens

·        Menus and menu sequences

·        Fields to be verified

·        Bar code types and Application Identifiers

·        Use of the Enter function
