SAP EWM: Rf Screen Programming

RF devices are external devices connected with the SAP EWM application through middleware such as the SAP console or ITS mobile. RF is a Radio Frequency in SAP EWM Mobile Data Entry which is used to execute all the warehouse activities in inbound, outbound, and internal warehouse activities through handheld devices. This document explains in detail the SAP EWM RF Framework and its features.

The connection between an RF device and SAP EWM can be established through ITS Mobile or SAP Console. This interface enables communication and data exchange between the two systems.

RF Device and Operation in SAP EWM

The RF device in SAP EWM consists of screens and buttons. These screens can be touch-activated or operated using predefined buttons or a keyboard. To initiate the process, the barcode on a label is scanned to retrieve document number or information. After each scan, the cursor automatically moves to the next available field for further scanning. Once all data is scanned, predefined function keys are used to execute or post the document as required. The standard barcode type for identification and verification in SAP EWM is EAN128. Customization and development of screens can be done using the standard RF screen manager, while menus and menu sequences can be defined using the standard RF menu manager. In SAP EWM, the standard screen size is 8×40 characters wide and long respectively.

SAP EWM RF Framework Features in Standard Format

The SAP EWM RF Framework offers a range of functionalities for users.

SAP EWM RF Framework Navigation in SAP

In order to complete a specific logical transaction, an operator is responsible for either inputting data, validating existing data, or both. To enter the necessary information, the operator can utilize an open input field where they can either scan barcodes or manually type in the required data. Once all necessary steps have been completed, the operator has the option to execute the process or finalize the transaction by selecting the appropriate function key push button.

RF screen in SAP EWM displays various menu options and transaction fields. The displayed information on the RF screen includes a range of choices for users to navigate through different functions and perform specific tasks within the system.

Understanding the RF framework in SAP EWM

The RF Framework in SAP EWM is a key technology used to automate and optimize warehouse processes. It enables various warehouse activities, such as picking, putting away, packing, counting, etc., to be managed and carried out efficiently and accurately.

SAP EWM RF Framework Configuration

The SAP EWM RF framework consists of different elements and configurations such as the RF Screen Manager, Display Profile, Presentation Device, Presentation Profile, Personalization Profile, and RF Menu Manager. These components play a crucial role in the functioning of the system.

RF Screen Manager in SAP EWM

The RF Screen Manager is a useful tool for adjusting the appearance of RF screens to match the characteristics of RF devices. It allows users to create, copy, edit, or remove display profile screens based on their needs. The display profile determines how RF screens look and includes screen templates and formats.

The warehouse operator has the ability to manage various screen display features by creating Display Profiles. These characteristics include screen size, the number of buttons on a screen, text length for buttons and menu items, how messages are shown on the screen, and screen numbers.

Presentation Device

The Presentation Devices enable the classification of the various devices that are being used in the warehouse. The presentation device settings have a display profile, presentation device type, data entry type, function keys, etc. These presentation devices can then be assigned to a warehouse operator based on their role in the warehouse. This is a part of EWM resource management.

Presentation Profile

The Presentation Profile, along with the personalization profile, supports different menu structures for different resources. The standard presentation profile is “****” which is assigned to the RF application (the standard application for SAP EWM is 01 ).

Personalization profile

The Personalization Profile enables the modification of the standard SAP menu and menu sequence. This will be assigned to resources as per the tasks assigned to them. With the personalization profile, the SAP EWM RF can enable the warehouse to create different RF menus to support different resource groups based on the warehouse processes to which they are assigned to. The standard RF personalization profile in SAP EWM is ‘**’.

RF Menu Manager in SAP EWM

Using the RF Menu Manager, warehouse operators have the ability to customize menus by adding menu items to both main and sub-menus.

Understanding the RF Screen in SAP

RF Screen Enhancement is a way to improve the programming of RF screens in SAP EWM. RF, or Radio Frequency, refers to the technology that allows data to be transmitted wirelessly through the air. In this case, it is used for sending and receiving data from a remote wireless scanner, such as an RF gun or handheld device.

The remote wireless scanner accepts data input from users and sends it to the nearest Access Point. An Access Point is a network device that acts as a bridge between the wireless scanner and a server. It enables communication between these devices by providing a connection to the server.

By enhancing RF screens in SAP EWM, we can make them more efficient and user-friendly. This means improving how information is displayed on these screens and making it easier for users to interact with them using their handheld devices. Overall, this enhancement helps streamline processes within SAP EWM by enabling seamless communication between remote scanners and servers via radio frequency technology.

RF Standard Function Keys in SAP EWM

In SAP EWM, there are certain predefined function keys that may not be visible on the RF screen but can still be performed.

• F5: More – In case you have more than 4 buttons on the screen, pressing F5 will display the next available buttons.
• F6: Clear – This will clear all the entered data on the RF screen.
• F7: Back – This will take the user back to the previous screen.
• F8: List – This will display the list of all possible input values for that field.
• F9: Full Message – This will show the full warning or error message that shows up at the bottom of the RF screen.

Creating a personalized RF screen in SAP: A step-by-step guide

To complete the task, follow these steps:

2. Proceed to update the newly created Display Profile (Z1) in the Presentation Device. Use T-code /SCWM/PRDVC for this step.

3. Next, log in to the RF Device using T-code /SCWM/RFUI.

Remember to carefully follow each step in order to successfully complete the process.

RF Transactions in SAP EWM

The EWM RF usage includes the use of various transactions that are important for its functioning.

What is the dimensions of the RF display in SAP?

SAP, the software provider, offers pre-designed screens that are specifically designed for a screen size of 8×40. These screens are optimized to fit within this particular dimension and ensure optimal functionality and usability. By using these standardized screens, you can enhance efficiency and accuracy in your warehouse management processes.

Additionally, keep in mind that user experience plays a crucial role in utilizing the RF screen manager effectively. Ensure that the font sizes used on these screens are easily readable on an 8×40 display without causing any strain or difficulty for users. Test different font styles and sizes before finalizing them to guarantee clear visibility during data entry tasks.

What size is the screen of EWM RF?

In SAP EWM, a standard RF screen size of 8X40 is provided. However, there may be instances where you need to convert this standard screen size to 16X20 without having to manually modify each individual screen using the screen painter tool.

Fortunately, there is an easier way to achieve this conversion. You can utilize the Screen Control Framework (SCF) functionality in SAP EWM. SCF allows you to define and manage screens in a more flexible manner by separating the layout from the logic.

To convert the standard RF screen size to 16X20 using SCF, follow these steps:

1. Create a new custom control for your desired screen size (in this case, 16X20).

2. Assign this custom control as an alternative control for all relevant fields on your existing screens.

3. Activate and test your changes.

By implementing these steps, you can effectively change the standard RF screen size without having to individually modify each and every screen through the traditional method of using the screen painter tool.
