Call POWL list with application confguration from ABAP webdynpro

I created a powl list (= YL_LOG_PLATFORM)  and a webdynpro application.

In my webdynpro application I call my powl list via following code (as described in several documents):

*  lv_qname = 'YL_LOG_PLATFORM1' .
  CALL FUNCTION 'POWL_ENCODE_SELPARA'
    EXPORTING
      i_selpara        = lt_query_params
*     I_ESCAPE         = '_line'
    IMPORTING
      e_selpara_string = lv_inbox_query.

  wd_this->fire_out_plg(
       applid    = 'YL_LOG_PLATFORM'
       qname     = ' '                  " lv_qname
       forallq   = 'X'
       qselpara  = lv_inbox_query
       refreshq  = 'X'
       refresha  = 'X'
       srvgroup  = ' '
        ).

This works fine.

Then I created an application configuration for the powl list.  Calling the powl list immediately via the application configuration works as well.

But now I want to call the powl list WITH the application configuration in the webdynpro. I do not see how I can give my application configuration name in the call. 

Ter info: I call the powl in a webdynpro because there are buttons on the powl that starts some webdynpro apllications.  Also the 'development' should work in the portal AND in R/3.

Any suggestions?
