1 Radio 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. For more information about the RF screen manager, see Customizing for Extended Warehouse Management under (RF) Framework RF Screen Manager .

Mobile Data Entry

Radio Frequency

Note SAP provides screens based on a screen size of 8x40.

Menu Personalization Using the RF menu manager, you can define your own menus and menu hierarchy for the RF device transactions. For more information about the RF menu manager, see Customizing for Extended Warehouse Management under Framework RF Menu Manager .

Mobile Data Entry

Radio Frequency (RF)

Note SAP provides a standard menu and menu hierarchy.

Standard RF Features The SAP RF framework provides standard RF features, including the following: Logon Logoff Recovery Work execution transactions for the following warehouse processes: Picking Putaway Loading Unloading Deconsolidation Packing Physical Inventory Replenishment

1.1 RF Navigation

PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 3 of 29

Purpose This section describes the process for navigating from RF menus to transactions, as well as navigation within transactions.

Process Menu Navigation The RF framework supports the following options for menu navigation to RF transactions: 1. Standard Navigation You choose the required menu item. 2. Direct Navigation to Transaction You enter the number of the required menu item displayed, in the Menu field. 3. Virtual Navigation Unlike the first options where navigation is accomplished from the displayed menus, this option enables “virtual” navigation between menus. You enter the numbers of all required menu items, including those not displayed on the current screen, but rather displayed on subsequent screens.

If on the main menu screen, you enter 415 in the Menu field, you navigate to the Pick by HU transaction.

Transaction Navigation When in the screen for a particular logical transaction, you may be required to enter data, validate existing data, or a combination of both. When data entry is required, the input field is open. You enter the data by scanning bar codes. If you enter data manually, you choose Enter after entering the value. Where the content provider fills fields with content, the input fields may either be closed, or hidden (depending on Customizing for Extended Warehouse Management → Mobile Data Entry → Radio Frequency (RF) Framework → Define Logical Transaction Step Profiles → Define Validation Profile ). Where the input fields are closed, you verify the values by scanning the bar codes. After all input fields on the screen are filled, one of the following occurs: ● If the Skip Shortcut indicator is set, the posting (for example, WT confirmation) is automatically triggered. ● If the Skip Shortcut indicator is not set, you automatically navigate to the Shortcut field.

You can set the Skip Shortcut indicator when maintaining screens via the RF screen manager. For more information, see the Implementation Guide (IMG) for Extended Warehouse Management → Mobile Data Entry → Radio Frequency (RF) Framework → RF Screen Manager. You can invoke functions by choosing the corresponding function key pushbutton, or entering the function key in the Shortcut field. Where necessary, you enter exception codes in the Shortcut field (for example, for differences).

You define exception codes in Customizing for Extended Warehouse Management → Cross-Process Settings → Exception Handling → Define Exception Codes.

1.3 Standard RF Functionalities Use The RF framework supports standard RF functionalities, including the following: ● Logon and logoff – implemented as steps within a master transaction ● Recovery – implemented as a state of the logon step ● Request work/inquiry – implemented as a step of the master transaction, which initiates another transaction

1.3.1 Logon PUBLIC © 2014 SAP SE or an SAP affiliate company. All rights reserved.

Page 6 of 29

Use Logon to the RF environment enables the tracking of

resources, stock on resources, and

warehouse order (WO) selection.

After logging on to the system, a resource can operate as an active resource, which can request and execute work in the warehouse.

Prerequisites You have logged on to the system.

Features Automatic and Manual Logon The RF framework supports automatic logon triggered by a presentation device, or triggered by a user. ● Triggered by Presentation Device (Background Processing) If a presentation device can identify itself (for example, by IP address), the application uses this identification to determine the default resource. User-related parameters are based on the predefined user’s default data. ● Triggered by User If a default resource and warehouse are defined for a user, and a default presentation device is defined for the default resource, then automatic logon occurs when the user chooses to logon to the RF environment. Depending on Customizing, the user may either be logged on automatically, or presented with the logon screen, with all default parameters displayed. For manual logon, a user must identify the resource to which he or she logs on, as well as the warehouse and presentation device. Multiple Logons The RF framework supports the logging on of a user to multiple resources.

Activities Logon Automatic Logon Triggered by Device 1.

Manual Logon Triggered by User

You define a user, using the user maintenance transaction ( Extended Warehouse Management → Master Data → Resource Management → /SCWM/USER - Maintain User on the SAP Easy Access screen).

2.

When defining the user, you must assign a When defining the user, you must define a On the SAP Easy Access screen, you default resource and default warehouse. default resource and default warehouse. choose Extended Warehouse The default resource must have assigned to Management → Execution → it a default presentation device.

3.

You define a presentation device, using the presentation device maintenance transaction ( Extended Warehouse Management → Master Data → /SCWM/PRDVC - Maintain Presentation Devices on the SAP Easy Access screen). When defining the presentation device, you must have assigned to it the default resource. The presentation device is one that is able to identify itself.

4.

● The device is defined in Extended Warehouse Management → Master Data → /SCWM/PRDVC - Maintain Presentation Devices on the SAP Easy Access screen. ● The device is assigned using the resource maintenance transaction ( Extended Warehouse Management → Master Data → Resource Management → /SCWM/RSRC – Maintain Resource on the SAP Easy Access screen).

When you turn on the presentation device, On the SAP Easy Access screen, you it calls SAPConsole, which initiates the RF choose Extended Warehouse presentation transaction, and logs on automatically.

/SCWM/RFUI - Log On to RF Environment. The logon screen appears. You enter the warehouse number, resource and presentation device with which to log on. One or more of these fields may be filled with default parameters, depending on your user and resource definitions.

If you do not fill the DefPresDvc field on the Logon screen, it is filled with one of the following:

● The default presentation device defined for the resource in the resource maintenance transaction ● The presentation device set as the default in the presentation device maintenance transaction, if no default presentation device is defined for the resource You choose Enter to log on.

Management → Execution → /SCWM/RFUI - Log On to RF Environment.

● If you set the Auto Logon indicator when defining the user, you are logged on automatically. ● If you did not set the Auto Logon

indicator, the Logon screen appears, with the fields being filled with the default parameters. You may either keep the default, or change any of them. You then choose Enter to log on.

If you set the Auto Logon indicator, multiple logons are not possible. 5.

During logon, the Dynpro layer identifies the display profile assigned to the specific presentation device. The business logical layer does the following:

● ● ● ●

Addresses the logon to resource management, to perform the logon process Fetches the resource’s personalization profile and authorization information. Determines the logical transaction associated with the physical transaction Sets the initial step and function code

The logon transaction ends only when you log off.

1.3.2 Logoff Use This function enables a

resource to log off from the RF environment.

Integration Logoff is a step of the logon logical transaction.

Activities 1. You choose F1 Logoff . 2. You enter a reason code for logging off and choose F1 Save . The resource’s logoff request is sent to

resource management, via the business logic layer package.

The resource is logged off from the RF environment. Depending on the reason code, the WOs assigned to the resource either remain assigned to it, or are unassigned.

1.3.3 Recovery Use During logon, the system checks with the content provider whether the user is logged on as a execution.

resource, and if so, whether he or she was interrupted during WO

Integration The recovery functionality is part of the logon transaction.

Activities 1. A user attempts to log on to the system. 2. The system checks with the content provider whether the user was previously logged on to the RF environment. a. If the user was logged on to a resource, see step 3. b. If the user was logged on to more than one resource, the logon screen is displayed with the RcvR e pushbutton, enabling the user to select the resource with which to continue. 3. The system checks whether a specific WO that was assigned to the resource was stopped before completion. It does so by checking for WOs that fulfill all of

the following conditions: a. The WOs are assigned to the resource b. The WOs have already been started c. The WOs can be locked 4. If the system finds any WOs that fulfill these conditions, it does the following: a. Finds the relevant logical transaction b. Finds the WO’s data c. Displays the screen of the relevant step 5. If the system does not find any WOs that fulfill these conditions, the system displays the Menu screen.

1.3.4 Position Management Use Position management enables an RF device user to validate handling units (HUs) by their position number, rather than by their HU number. This is particularly useful when the HU number tags are not readily accessible, such as when the HUs are stacked on top of each other.

Prerequisites In Customizing for Extended Warehouse Management → Cross-Process Settings selected one of the following options for the Pos.Mgmt field:

→

Resource Management

→

Define Resource Types , you have

● Manual ● Automatic

Activities 1. An RF user logged on as a

resource navigates to the pick HU introduction screen (0200) and scans a pick HU.

2. If the resource’s resource type has automatic position management, the following occurs: a. The scanned HU is assigned to the next available position. b. The cursor moves to the next HU input field. 3. If the resource’s resource type has manual position management, the following occurs: a. The cursor moves to the position field. b. The resource manually enters the position number. c. The HU is assigned to the position. d. The cursor moves to the next HU input field. 4. In the background, an internal warehouse task (WT) is created to update the HU location and logical position.
