Function documentationRadio Frequency Framework

 

Extended Warehouse Management (EWM) includes the implementation of a radio frequency (RF) framework satisfying the following objectives:

  • Decouples business logic from the physical presentation of application data on a selected presentation device

  • Supports a large variety of device sizes, device types, and data entry types

  • Provides appropriate forms of data presentation according to application data, device capabilities, and user preferences

  • Calls appropriate services according to resource inputs (such as verification/input data, keystroke, or logon request)

  • Enables personalized menus and screens

  • Enables flexible and user-friendly screen and flow logic generation and modification

By providing an RF framework, greater efficiency and fast, error-free data communication can be attained in the warehouse, through the use of mobile RF devices.

Features

Support for GUI and Character-Based Devices and Browser-Based Devices

The RF framework supports both GUI and character-based devices, as well as browser-based devices.

GUI devices are connected to the SAP system just like any other client-dependent PC. The screens can be touch screens, using predefined pushbuttons, or they can be operated using a keyboard. If you are using touch screens, you simply touch the appropriate positions on the touch screen instead of clicking with the mouse on a pushbutton.

Character-based devices are linked to the system through SAPConsole. SAPConsole operates on a 32-bit Windows server and interacts with the RF terminals connected to it. This concept is currently supported by the leading providers of RF terminals.

The system uses ITSMobile for connecting browser-based devices.

Bar Code Support

The RF framework supports the use of bar codes for identification and verification purposes. SAP currently supports EAN 128 bar code types, but you can also support other types within the RF framework.

Screen Layout Personalization

Using the RF screen manager, you can customize the appearance of RF presentation screens, so as to ensure that they are consistent with the attributes of the presentation devices being used.
