Queries related to POWL...

Question

Hi Experts,
I have couple of queries related to POWL:
1.  Is it possible to select multiple rows in the POWL query table (Result after runnig POWL query). I am not using Web Dynpro ABAP application to call POWL but using POWL iView.
2.  If above is not possible then can multiple rows be selected by pressing CTRL button and then lead select with the help of mouse. I am not able to do this as well. In one of the ECC it is working but in other it is not working. can there be any version issue.
3. By default Layout of POWL query are Link Matrix and the same can be changed to Tabstrip by going inside Personalize option, but that will only affect the particular user who have done personalization.
Is there any way to make Tabstrip Layout as default for all the users.
4. Please through some light on transaction LPD_CUST, as I want to open Web dynpro screen from POWL action. Again POWL is not embedded in Web dynpro application.
Thanks,
Harish

Thanks Manas for your response.
I have gone through one of the posts in which you have explained about this transaction LPD_CUST and that is how I have came to know about it.
Link: [Calling Web Dynpro application or URL from POWL;
but after this code is executed I am getting Null Pointer exception.
i.e. field like MR_LAUNCHER_CLASS & MR_WD_APPLICATION in INITIAL and that is why the below statement (Standard code) is giving null pointer:
ld_client_environment = mr_wd_application->get_client_environment( ).
Also just wan tto know the significance of Role and Instance (I have just taken any dummy name).
Code which I have written is below:
cl_apb_launchpad_api=>read_for_display(
        EXPORTING
          id_role                     = 'ZTESTROLE'
          id_instance                 = 'ZTESTINSTANCE'
          ir_provider                 = lr_provider
        RECEIVING
          er_launchpad                = lr_lpd_handle
       EXCEPTIONS
         parameter_missing           = 1
         not_found                   = 2
         others                      = 3
      IF sy-subrc <> 0.
      MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
                 WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
      ENDIF.
      CHECK lr_lpd_handle  IS BOUND.
      IF lr_lpd_handle IS BOUND.
      ENDIF.
      lt_lpd_content = lr_lpd_handle->get_content( ).
      READ TABLE lt_lpd_content REFERENCE INTO lr_lpd_content WITH KEY link_text = 'TESTWEBDYNPRO'. "Link text for launchpad
ls_appl_param-key = 'SAP-WD-CONFIGID'. "app conf if any
     *ls_appl_param-value = 'MDG_OIF_CREATE_CONF'.
     *APPEND ls_appl_param TO lt_appl_param.
      lt_lpd_appl_params = lr_lpd_content->application_parameter.
      "launch application
      lr_lpd_handle->launch_application(
        id_application_id         = lr_lpd_content->application_id
        it_application_parameters = lt_lpd_appl_params
  it_business_parameters =  lt_appl_param
