Application Parameters and URL ParametersLocate this document in the navigation structure

Use

You can control the Web Dynpro ABAP runtime or the Web Dynpro ABAP application by inserting the URL query string parameter into the request URL. To do this, you simply extend the URL in the browser:

        
<scheme>://<host>.<domain>.<extension>:<port>/sap/bc/webdynpro/<namespace>/<application name>?<parameter name>=<parameter value>
Example

http://us7211.wdf.sap.corp:50021/sap/bc/webdynpro/sap/demo_table?sap-language=EN

Parameter names and parameter values are not case sensitive (exception: sap-exiturl, if a server is linked that does differentiate between upper and lowercase). You can combine several parameters in one URL.

Caution

Be aware of the security issues relating to URL and application parameters. For more information, see Data Security in Web Applications.

The parameters are listed on the pages below:

Setting Parameters

You can set URL and application parameters in the following places:

  • In the Web Dynpro application (in transaction SE80 in the Web Dynpro explorer for the application on the Parameters tab page). You can either define new parameters or select a predefined parameter and assign a value to it.

  • In the application configuration (Web Dynpro application CONFIGURE_APPLICATION, tab Parameter).

  • Globally for all applications and a specific client using Web Dynpro application: WD_GLOBAL_SETTING Call Web Dynpro ABAP application WD_GLOBAL_SETTING, and enter the value you want the parameter to be for all applications.

  • For the user and all applications (with user parameters – only possible for a few parameters).

  • For the current call (as a URL parameter – in this case, the parameter names are not case-sensitive).

Order of Evaluation

The setting options are evaluated in the order below:

  1. In the parameters determined by the URL
  2. The standard parameters defined for the Web Dynpro application

A URL parameter always overrides an application parameter. The logon language is determined or proposed from the sources listed below: These sources are evaluated in the order below whereby the first in the list is the decisive source.

  1. URL parameter sap-language
  2. Default language in the setting for the System Logon for the Configuration Settings
  3. Web browser languages (Accept-Language)
  4. Default language of ABAP system
Note

The language from the user account is not evaluated in the ABAP system. The language you want must have been installed in your system.
