Name of the user parameter: ACCESSIBILITY_MODE Specifies which screen reader support is used. No value specified: ARIA-compatible role attributes (landmarks) are used. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE. X: SAP's own support for screen readers This setting is recommended for optimal support. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE. ARIA-compatible support for screen readers in compliance with W3C ARIA standard. The controls are described with ARIA attributes. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE.
WDACCESSIBILITYMODE/ SAP-ACCESSIBILITYMODE	No value specified CLASSIC (default value) ARIA	Specifies which screen reader support is used. No value specified: ARIA-compatible role attributes (landmarks) are used. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE. CLASSIC: SAP's own support for screen readers This setting is recommended for optimal support. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE. ARIA-compatible support for screen readers in compliance with W3C ARIA standard. The controls are described with ARIA attributes. GET_ACCESSIBILITY( ) API returns value ABAP_FALSE.
WDALLOWUSERAGENTS / -	TOLERATED (default value) SUPPORTED	Specifies in which browsers Web Dynpro applications can be run. TOLERATED: Users can also run Web Dynpro applications in browsers that are supported by Unified Rendering browser recognition even if these browsers are not supported by SAP in accordance with the Product Availability Matrix (PAM). SUPPORTED: To specify that Web Dynpro applications can only be run exclusively in SAP-supported browsers (in accordance with PAM), you set the parameter to value supported. For more information, see Changing the Default Browser Detection.
WDALLOWMULTIPLEACTIONS / WDALLOWMULTIPLEACTIONS	X (default value) No value specified	Specifies that more than one action per roundtrip can be processed. For more information see Multiple Actions per Roundtrip in Phase Model.
WDALLOWQUICKVIEWS / -	X (default value) No value specified	Specifies whether quick views are to be available or not. The parameter cannot be forwarded as a URL parameter. Administrators can set this parameter as an application parameter in the global settings. The application can use IF_WD_APPLICATION->GET_QUICKVIEWS_ALLOWED() to import the parameter during runtime. Note If the application is running in accessibility mode, the result is always abap_false because quick views cannot be displayed in this mode.
WDALLOWVALUESUGGEST / WDALLOWVALUESUGGEST	ON (default value) OFF No value specified	Activates and deactivates the function for Suggested Values for Input Fields. In addition, the suggested value function must be activated in transaction SDSH_CONFIG.

-/ SAP-WD-LOADONDEMAND	X (default value) No value specified	The JavaScript sources for individual Web Dynpro ABAP UI elements are first loaded by default from the ABAP server and cached in the browser when they are needed for the first time. This saves resources because the smallest amount of JavaScript code is loaded from the browser and cached. In some cases this behavior is not wanted or necessary. If SAP-WD-LOADONDEMAND is not activated, all JavaScript sources are packed in a file and sent to the browser. The amount of JavaScript code to be cached is much greater in this case but also no longer needs to be loaded.
-/ SAP-WD-SILVERLIGHTDEBUG	X No value specified	This parameter is needed to debug a Silverlight application. If the Web Dynpro application is openede with URL parameter SAP-WD-SILVERLIGHTDEBUG=X, the debug file is automatically used instead of the .swf file for the SilverlightIsland.

To display the view element adapter IDs, call technical from the running application, and navigate to the View Element Adapter tab. The IDs are listed in theView Element Adapter IDs column. Name of the user parameter: WD_STABLE_ID_F_TEST The user parameter does not work in productive operation.
-/ SAP-WD-SUPPRESSCUSTOMHTML	X No value specified	With this parameter, you control whether HTML is suppressed, which was specified with an HTMLIsland, HTMLContainer, or HTMLFragment. You can use the parameter to check whether an error due to incorrect customer-defined HTML occurs.
WDDISPLAYLOADINGPAGE/ SAP-WD-DISPLAY-LOADINGPAGE	0 (default value) 1 2 4 5 6	This parameter controls the startup behavior of a Web Dynpro ABAP application. Values 4, 5, and 6 should only be set if problems occur with session handling. 0: Default value. Start with 2 roundtrips Value 0 is the default value. The Web Dynpro ABAP application starts with two roundtrips. In the first roundtrip information about the browser environment can be ascertained and forwarded to the application. 1: Start with 1 roundtrip Value 1 starts the application with one roundtrip. 2: Start with 2 roundtrips Value 2 starts the application with two roundtrips. In the first roundtrip information about the browser environment can be ascertained and forwarded to the application. 4: Start with 1 roundtrip with callback to ICM. Value 4 is used if session handling problems occur when starting with one roundtrip. With value 4 the Web Dynpro ABAP applications also starts with one roundtrip. When the application starts, the ICM is informed through the session used. Value 4 only functions with external session handling, as is the case with Enterprise Portal, NWBC, and Fiori Launchpad. 5: Start with 2 roundtrips, timeout for 1. Request after approximately 60 seconds. Values 5 and 6 are used if session handling problems occur when starting with two roundtrips. Values 5 and 6 start the Web Dynpro ABAP application also with two roundtrips. In the first roundtrip the timeout of the session is severely reduced. As soon as the second roundtrip reaches the session, the timeout is reset to the original value. If the second roundtrip is delayed or canceled, the session in the background is automatically deleted after a short time. This is recorded in the system log. Values 5 and 6 can be activated with application parameter WDDISPLAYLOADINPAGE. The values can be deactivated with URL parameter sap-wd-display-loadingpage. 6: Start with 2 roundtrips, timeout for 1.
