Hi All,
I have a report output with REUSE_ALV_HIERSEQ_LIST_DISPLAY with custom PF Status and i have a custom button which call a CLass (Which perform some function at the background which the user doesn't notice) afterreturning from class
but now it displays a blank screen.
To overcome come this i called PERFORM OUTPUT again immediately after calling the class , now it diplays the out screen and user doesn't notice any difference but the problem is when i press the BACK button now it displays blank screen the back button.
When ever the control returns after calling the class it displays a blank screen
form output.
CALL FUNCTION 'REUSE_ALV_HIERSEQ_LIST_DISPLAY'
      EXPORTING
        i_callback_program       = v_repid
        i_callback_pf_status_set = 'SET_PF_STATUS'
        is_layout                = s_layout
        it_fieldcat              = t_fieldcatalog
        i_callback_user_command  = 'USER_COMMAND'
        i_tabname_header         = 'Itab'
        i_tabname_item           = 'Itab1'
        it_events                = t_events
        is_keyinfo               = s_keyinfo
*        i_buffer_active          = 'A'
      TABLES
        t_outtab_header          = itab
        t_outtab_item            = itab1
      EXCEPTIONS
        program_error            = 1
        OTHERS                   = 2.
endoutput
Thanks in advance.

Answer 1

Hi
1.Check if v_repid is populating correctly or not
2. pass ITAB & ITAB1 in capital letters
        i_tabname_header         = 'ITAB'
       i_tabname_item           = 'ITAB1'
Hope this will solve the error.
