General Information

Currently, the work process in the warehouse is characterized by speed, reliability, and precision

processing of 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. Through paper-free communication using mobile data processing techniques, it is possible

to achieve rapid error-free data communication. This, in turn, leads to a high standard of quality.With the implementation of remote radio frequency (RF) terminals, particularly in large warehouse

complexes, you can avoid cost-intensive input errors in the system and loss of time needed for

covering distances within the warehouse.

With this release, SAP provides direct RF functionality that will meet the above requirements. This

RF connection was possible in earlier R/3 releases only by using complementary software. RF

terminals receive data directly from the R/3 System and return the data results to the system. You

can scan information that needs to be recorded, such as transfer order or material numbers, using a

combined bar code (e.g. based on EAN128 standards). You can also use the bar code scan to verify

the storage bins.

The display of information is possible on an RF terminal 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 its own, non-graphic user interface.

Description of Usability Enhancement

With the help of the RF link, the system walks the warehouse staff through the warehousing

activities step-by-step. The material flow forms the basis for orientation. For example, the system

provides the user with information as to where to pick up a particular item and to which destination

it needs to be moved.

Putaway and Picking Activities

The system displays information about the transfer orders for the employee in the warehouse

directly on the hand-held (or panel mount) terminal. No picking list needs to be printed. There are

several ways to determine which transfer order needs to be processed next.

• You can display an order directly by scanning a bar code

• You can assign individual transfer orders to employees by defining user profiles

The processing steps for the individual transfer orders are displayed on the terminal one after the

other. After they have been confirmed, the system displays the next movements. If further

information is required, you can branch to a detailed display of the item. If the quantity in the

transfer order does not match the physical quantity, you can report the differences back to the

system.

To make sure that you have processed the correct storage bin, you can compare the information in

the storage bin with the data in the transfer order (through scanning or manual entry). The way you

set up this verification function in the system is very flexible.

Posting Change Activities

The system guides you through the posting change orders (used for changes in material status) in

the warehouse in much the same way as it does for putaways or picks.

Inventory

Instead of the counting lists used up to now, the inventory process now uses the hand-held terminal.

You can take inventory either by initiating a physical inventory document and assigning it to an

employee, by scanning, or by manually entering the appropriate storage bin.

In warehouses where putaway and picking takes place using complete units (for example, in pallet

storage) the storage units (SUs) can be entered without specifying a material or quantity. You takeinventory by scanning the SU labels. With this new method of inventory taking, the system only

includes the individual SUs in the storage bin and the system determines the quantity automatically.

Query of Stock Situation in the Warehouse

This function displays information about the material stock and supports the selection of data using

various criteria.

Future Plans

We will continue to enhance the RF functionality to cover all operations in the warehouse and

transportation area.

Packaging Functions

During picking of transfer order items, you can specify at an RF terminal which materials are to be

picked in individual shipping units. Further functions in the packaging area will be included

gradually in the RF link (for example, load control) in order to ensure optimal support of supply

chain activities.

Task Management

In the future, it will be possible to split transfer orders into individual tasks and to execute each of

these tasks using an RF connection. Here we will use the liveCache technique.
