 Logon

Use

Logon to the radio-frequency (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 default data of the user.

  • 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

You define a user, using the user maintenance transaction (Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step Resource Management Next navigation step /SCWM/USER - Maintain User End of the navigation path on the SAP Easy Access screen).

Automatic Logon, Triggered by Device

Automatic Logon, Triggered by User

Manual Logon

When defining the user, you must assign a default resource and default warehouse.

When defining the user, you must define a default resource and default warehouse.

The default resource must have assigned to it a default presentation device.

  • The device is defined in Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step /SCWM/PRDVC - Maintain Presentation Devices End of the navigation path on the SAP Easy Access screen.

  • The device is assigned using the resource maintenance transaction (Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step Resource Management Next navigation step /SCWM/RSRC – Maintain Resource End of the navigation path on the SAP Easy Access screen).

On the SAP Easy Access screen, you chooseStart of the navigation path Extended Warehouse Management Next navigation step Execution Next navigation step /SCWM/RFUI - Log On to RF Environment. End of the navigation path.

The logon screen appears.

You define a presentation device, using the presentation device maintenance transaction (Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step /SCWM/PRDVC - Maintain Presentation Devices End of the navigation path on theSAP 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.

When defining the user, you must define a default resource and default warehouse.

The default resource must have assigned to it a default presentation device.

  • The device is defined in Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step /SCWM/PRDVC - Maintain Presentation Devices End of the navigation path on the SAP Easy Access screen.

  • The device is assigned using the resource maintenance transaction (Start of the navigation path Extended Warehouse Management Next navigation step Master Data Next navigation step Resource Management Next navigation step /SCWM/RSRC – Maintain Resource End of the navigation path on the SAP Easy Access screen).

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

When you turn on the presentation device, it calls SAPConsole, which initiates the RF presentation transaction, and logs on automatically.

On the SAP Easy Access screen, you choose Start of the navigation path Extended Warehouse Management Next navigation step Execution Next navigation step /SCWM/RFUI - Log On to RF Environment. End of the navigation path

  • 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.

    Note Note

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

    End of the note.

You choose Enter to log on.

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 personalization profile of the resource, 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.
