Hi,
Application parameters can be used for this accessed directly only in the Window. Follow these steps;
1. get the application url using the following code,
par_wrkitm is the application parameter ( which should also be declared in the HANDLEDEFAULT method of the window as importing parameter and aslo appended in the URL )
g_wrkitm is a Component Controller attribute
Data: my_url TYPE string.
*Get the URL of the Application
CALL METHOD cl_wd_utilities=>construct_wd_url
EXPORTING
    application_name = 'ZWDRC_NEW_APP'
IMPORTING
   out_absolute_url = my_url.
2. Now pass the required parameter ( i.e in this case Workitem id ) to this URL
3. In your webdybpro applicatio, Goto Application parameters and create a parameter for workitem id with the same name as used in the URL.
4. In the HANDLEDEFAULT method of the window, create Importing parameters with same names as that of your application parameter.
5. Now this variable will contain your workitem id.
If you want to acess the variable in your views;
2. create a attribute in the Component Controller( Component Controller->Attributes Tab; mark it as public )
3. Now in the HANDLEDEFAULT method of the window, assign your application parameter values to the component controller attributes directly as shown below,
wd_comp_controller->g_wrkitm = par_wrkitm
