Execute in Back ground when push button clicked on alv output

Question

Hi Friends,
I have a alv list display report with check boxes and a 'Detail' Push button in output
when i check the check boxes and click on the 'Detail' Push button detail report is
displayed using 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'. My requirement is if I click on 'Detail'
push button the code should also execute in back ground creating the spool. Request you
to help with sample code. I tried with below but not working.
WHEN 'DETAIL'.
      call function 'START_OF_BACKGROUNDTASK'
      exporting
       startdate = sy-datum
       starttime = sy-uzeit
      exceptions
      others    = 1.
      if sy-subrc = 1.
       exit.
      ELSE.
       PERFORM determine_table_from_output CHANGING rs_selfield.
       PERFORM call_alv_detail.
      endif.
     commit work.
Thanks,
Neetha.

You could encapsulate the detail display in a separate report and call it in your 'DETAIL'-section like this:
DATA: lv_number TYPE tbtcjob-jobcount,
           lv_name   TYPE tbtcjob-jobname,
           ls_rsparams TYPE rsparams,
           lt_rsparams LIKE STANDARD TABLE OF ls_rsparams.
*           Get free job number
             CALL FUNCTION 'JOB_OPEN'
               EXPORTING
                 jobname          = lv_name
               IMPORTING
                 jobcount         = lv_number
               EXCEPTIONS
                 cant_create_job  = 1
                 invalid_job_data = 2
                 jobname_missing  = 3
                 OTHERS           = 4.
             IF sy-subrc = 0.
               SUBMIT 'ZDISPLAY_DETAIL'
               VIA JOB lv_name NUMBER lv_number
               WITH SELECTION-TABLE lt_rsparams
               AND RETURN.
               IF sy-subrc = 0.
*                Submit
                 CALL FUNCTION 'JOB_CLOSE'
                   EXPORTING
                     jobcount             = lv_number
                     jobname              = lv_name
                     strtimmed            = 'X'
                   EXCEPTIONS
                     cant_start_immediate = 1
                     invalid_startdate    = 2
                     jobname_missing      = 3
                     job_close_failed     = 4
                     job_nosteps          = 5
                     job_notex            = 6
                     lock_failed          = 7
                     OTHERS               = 8.
              ENDIF.
