Hello Diwakar,
Based on your query i understand that you need to embed your powl into a web dynpro application to view it.
u can do it in two ways..
the first one is just for testing..
prerequisites...
just check ur web dynpro service is activated.
Use transaction SICF
On the Maintain Service screen leave the default values as they are and choose Execute
In the Virtual Hosts/ Services tree control locate the node sap/bc/webdynpro. Right click on
the node and choose Activate Service from the context menu.
1. Navigate to the initial screen of the SAP Easy Access Menu.
2. Do a right-click on Favorites and choose Add other objects from the context menu.
3. Choose Web Dynpro Application from the upcoming dialog box list.
4. On the Web Dynpro Application subscreen, make the following entries.
Web Dynpro Applicat.-->POWL
Parameter -> APPLID   (Be sure to select the parameter via input help.)
Value ->Specify the APPLID defined for the POWER List to test.
Leave rest unchanged.
click OK.
By double-click on the created favorite, the specified POWER List will be displayed in a separate
Browser window..Only the basic functionalities can be tested this way.
The second way is in which you manually insert a powl component in web dynpro appl..
1. create a web dynpro component.
2. Specify POWL_UI_COMP as the used component in the properties and give a suitable name.
3. In the main view. insert a ViewcontainerUIelement.
4. In the component controller properties . click on create controller usage. and select POWL_UI_COMP
INTERFACECONTROLLER
5. Go to the windows selection and right click and select embed view on the ViewcontainerUIelement of the Main view. select POWL_MASTER from input help.
6. Create an outbound plug , name it as 'OUT'. link it with DEFAULT plug by dragging.
7.Go to the methods tab and in the Handle Default method .
and paste the following code..
  DATA: lv_inbox_query TYPE string,
        lt_query_params TYPE rsparams_tt,
        lwa_param TYPE rsparams.
  DATA lv_qname TYPE POWL_QUERY_TY.
lv_qname = 'QUERY1'.
  CALL FUNCTION 'POWL_ENCODE_SELPARA'
    EXPORTING
      i_selpara        = lt_query_params
      i_escape         = '\'
    IMPORTING
    e_selpara_string = lv_inbox_query  .
    wd_this->fire_out_plg(
      applid =  'POWLappl'                          " powl_applid_ty
      forallq =   'X'                        " powl_xflag_ty
      qselpara =   lv_inbox_query                       " string
      refresha =   'X'
      refreshq = 'X'                    " powl_xflag_ty
      srvgroup =   'X'
      qname =    lv_qname                " rzlli_apcl
where QUERY1 is the name of your default query and POWLappl  is your powl applid.
7. create application and test
