SYSTEM_PUBLIC 
Definition
BSP application SYSTEM_PUBLIC is a sample application for BSP application developers who want to adapt the individual fields of their logon screen, which is switched using the redirect to SYSTEM, user-specific to their BSP application.
Under no circumstances whatsoever should you make changes to BSP applications SYSTEM or SYSTEM_PUBLIC!
Use
you are using SYSTEM_PUBLIC to construct the URL that you enter as the redirect URL in Transaction SICF for your node in the service tree.
Prerequisites
...
1. Close all browser windows so that the browser can save no authentication information whatsoever.
2. Before you start SYSTEM_PUBLIC, ensure that you are not logged on to PSE management (Single Sign On).
If you are already logged on, then
log off PSE management, by clicking on the appropriate symbol on your desktop
and choosing Log off.
3. In the Object Navigator (Transaction SE80) enter SYSTEM_PUBLIC as the BSP application and choose Display.
4. Position the cursor on page default.htm of SYSTEM_PUBLIC and choose function key F8 (Test/Execute).
5.
The browser
logon screen is displayed, such as:
Choose Cancel.
You must not log on here, so that the browser does
not store your basic authentication.
6. You branch to a browser window with an address, such as:
7. In the URL, replace bc with public.
SYSTEM_PUBLIC is now displayed.
BSP application SYSTEM_PUBLIC runs under the general
display user SAPSYS.
This has the advantage that the browser has no authentication information and that each
initial request for a private BSP application results in an authentication
process. If BSP application SYSTEM is used, it is then
started.
Structure
SYSTEM_PUBLIC looks as follows:
From this interface you can try the different design options for a logon screen. You can hide and display individual fields, or assign them with default values. The aim is to construct a URL which you can then save in SICF with the redirect URL.

Page with information about the option of having a password sent by e-mail. |
BspSignUpHere |
../<public
BSP-App>/<page name.htm> |
Page with the option of registering for a specific SAP Web AS System. Registration always refers to a SAP Web AS System as a whole. As soon as authentication information is available, users can see all available BSP applications. |
BspClient |
BspClient=100 BspClientVisible=X |
Client and client visibility. If
you do not want to display the client, then write:
To
override the hard-coded client, use bspClient=<%=SYMANDT%> in
Transaction SICF. |
BspLanguage
|
BspLanguage=EN BspLanguageVisible=X |
Language and language visibility setting. If
you do not want to display the language, then write: |
BspSysIdVisible
|
BspSysIdVisible=X |
System ID visibility. The system ID is the name of the SAP Web AS System. |
BspAccessibility BspAccessibilityCheckboxVisible |
BspAccessibility=X BspAccessibilityVisible=X
|
Specify the accessibility and
visibility of a checkbox: This option sets an internal flag in the BSP runtime, which can be used by BSP applications to output additional information in the HTML output stream, so that screen reader programs can better present the visual information on the screen. BSP extensions HTMLB, XHTMLB und PHTMLB use this flag to change its rendering behavior. These parameters are not used after the logon.
Note that setting this indicator does not make any statement about that application’s accessibility. The indicator merely indicates that additional help is required for that application. |
BspChangePassword |
BspChangePasswordVisible=X
|
Data for changing the password. |
BspDontShowHttpsWarning |
BspDontShowHttpsWarning= |
Suppresses the warning created if there is no HTTP available.
The warning is issued in the default setting, because then passwords cannot be transferred securely (encrypted) over the Internet. |
BspDontForceHttps |
BspDontForceHttps= |
Prevents the use of HTTPS.
This parameter is available as of SAP Web AS 6.20 SP 28. We recommend you use this together with BspDontShowHttpsWarning. |
BspUserLongNames |
BspUserLongNames= |
Specifies long user names. |
BspDumpFields |
BspDumpFields= |
Additional information which is listed under the SYSTEM logon screen and which is used for testing and debugging.
Always switch these dump fields off before you generate your URL. |
BspSAPGUILayout |
BspSAPGUILayout=X |
Place the logon dialog in the top left corner of the browser. |
With
parameters BspPrivacyStatement, BspTermsOfUse, BspForgotPass, BspPasswordHint,
BspPasswordViaEmail and BspSignUpHere, always enter the relative or absolute
path for the page that you want to jump to.
Ensure that it should be a page that is located in an active application
(PUBLIC), which
can also be reached using an anonymous display user. This page must not be
located in the BSP application entered above, which uses SYSTEM.
Note that SAP does not provide the pages specified above with functionality for creating new users or resetting a password, for example. Whilst these pages are available in SYSTEM_PRIVATE, they are only empty shells for the type of services that are usually provided as Internet applications. Each application must decide which services it wants to provide behind these empty exit URLs, or if it wants to use them at all.
You can use pushbutton execute login to display how the logon screen will appear after you have made your modifications and to determine the correct URL for SICF.
