The use of universal product codes (bar codes) printed on consumer product packages, pallets and other containers has become a worldwide standard, not only for product identification and cost management at supermarket check-out counters, but also for inventory control and the optimization of stock movements in the warehouse.

The use of hand-held terminals or other scanning devices can easily be supported for WM transactions as a means to actually carry out physical goods movements.

The scanning of bar codes can be carried out in two ways:

• Using a hand-held RF/IR device with an MM-MOB interface to R/3

• By connecting a bar code reading device via a keyboard filter to the keyboard entry port of the PC. This method is a standard procedure and widely used by many customers. It is easy to implement, since the bar code reader acts just like a keyboard. This supports data entry at defined physical locations where you have an SAP terminal.

In WM, bar code scanning is primarily used to confirm transfer orders. Using bar code reading devices as described above enables your system to scan bar codes that are printed on transfer order documents and other container documents.

Using SAPScript, not only is it possible for you to print text on warehousing documents, you can also print bar codes as a standard procedure in WM. The WM default is to print bar code EAN 39. However, once the printer is installed to print bar codes, it is easy to print selected document numbers or other bar code types.

Several data processor manufacturers offer equipment with the capability to read bar codes to effectively support your application. For a list of certified partners, see internet address http://www.sap-ag.de/ (SAP's home page in Walldorf).
