CALL FUNCTION IN NEW TASK -> REFRESH screen.

sjk1977 — Mon, 16 Apr 2012 11:18:03 GMT

Hello Guys,

following situation:

a screen (5000) with a custom control.
custom container (cl_gui_custom_container) is bound to the custom control
within the custom container is a html viewer (cl_gui_html_viewer)
a function module is started 'IN NEW TASK' and checks database changes. If there is a change in database, the module ends and calls a form routine.
in this form routine i try to jump to the PAI with 'SET USER-COMMAND 'CHG' '

Problem -> the jump to the PAI is not working (ends in nirvana). One exception: i press on screen before data changes occurs. Then the programms calls the PAI.

Any idea why or how to solve the problem.

THX for your answers.

Some Code:

Screen 5000:

PROCESS BEFORE OUTPUT. MODULE STATUS_5000. MODULE init_control_processing_5000. PROCESS AFTER INPUT. MODULE USER_COMMAND_5000.

MODULE init_control_processing_5000.

MODULE init_control_processing_5000 OUTPUT. IF go_cont_head IS NOT BOUND. "Kopfbereich CREATE OBJECT go_cont_head EXPORTING container_name = 'CONT_HEAD' EXCEPTIONS OTHERS = 1. CREATE OBJECT go_html_head EXPORTING parent = go_cont_head. IF sy-subrc <> 0. ENDIF. CALL FUNCTION 'WDY_CONSTRUCT_URL' EXPORTING application = 'ZMM_ZK_HEAD' IMPORTING out_url = l_url EXCEPTIONS invalid_application = 1. g_url = l_url. go_html_head->show_url( g_url ). CALL FUNCTION 'STARTE_TASK' EXCEPTIONS communication_failure = 1 system_failure = 2. ENDIF.

ENDIF.

ENDMODULE.

Function module 'STARTE_TASK'

FUNCTION starte_task . *"---------------------------------------------------------------------- *"*"Lokale Schnittstelle: *" EXCEPTIONS *"      SYSTEM_FAILURE *"      COMMUNICATION_FAILURE *"----------------------------------------------------------------------CALL FUNCTION 'ZMM_ZK_HOLE_SCANNER_DATEN'
     STARTING NEW TASK g_scanner
     DESTINATION IN GROUP 'parallel_generators'
     PERFORMING refresh ON END OF TASK
     EXPORTING
       scannername = g_scanner.
ENDFUNCTION.

MODULE USER_COMMAND_5000.

DATA: l_url_200 TYPE char200,
         ls_data TYPE zmm_zk_scan.

   CASE sy-ucomm.
     WHEN 'EXIT'.
       LEAVE PROGRAM.
     WHEN 'BACK'.
       LEAVE TO SCREEN 1000.
     WHEN 'CANC'.
       LEAVE TO SCREEN 1000.
     WHEN 'CHG'.
       READ TABLE gt_data INTO ls_data INDEX 1.

       CONCATENATE g_url
                   '&mat='
                   ls_data-mat
              INTO l_url_200.
       go_html_head->show_url( l_url_200 ).
       CALL METHOD go_html_head->do_refresh
         EXCEPTIONS
           cntl_error = 1.

       CALL FUNCTION 'STARTE_TASK'.

       CLEAR sy-ucomm.

ENDCASE.
ENDMODULE.

Hi,

Why don't you write the logic of PAI for change in FORM refresh.?. Also you can use events ( OO ABAP ) to achieve this.

Hope this helps u.,

Thanks & Regards,

Kiran.

Hi,

Have you already tried the cl_gui_timer class?

Try using statement suppress dialog http://help.sap.com/abapdocu_70/en/ABAPSUPPRESS.htm -

After the PBO processing, the system triggers the event PAI in such as way, as if a user had pressed Enter
