Problem with Back button in ALV Grid

[Former Member]

Hello Guru's,

I developed one Z-program using  CL_GUI_ALV_GRID &   CL_GUI_CUSTOM_CONTAINER in which i was copied GUI status MAIN100 from standard program  BCALV_GRID_DEMO.  Program working fine as per the bussiness logic but When I Press BACK button in ALV Grid Output screen.. It was not going back to Selection-screen. one Blank screen appearing first and then on second (BACK)click it was going to Selection screen. Here I want to avoid blank screen.

Could you please help me out and do the needful.

Regards,

hi,

While you check user command, Try using Leave to screen 0 on 'BACK', and check whether back button is assigned same command text or not.

Hi,

You first activate your PF-STATUS for this copied program.

or

write code

if sy-ucomm.   " for back button

leave screen to 0.

endif

but first try to activate your copied programs PF-STATUS.

Hi

you just tell him which screen schould be displayed, so when BACK,  leave to screen 0.

in PAI .

MODULE PAI INPUT.

*   to react on oi_custom_events:

     call method cl_gui_cfw=>dispatch.

   CASE OK_CODE.

     WHEN 'EXIT'.

     leave screen to 0.

     WHEN OTHERS.

*     do nothing

   ENDCASE.

   CLEAR OK_CODE.

I hope, it will help you .

Regards

I ran into similar (same) issue, the cause in my case was a SKIP statement in SELECTION-SCREEN. The BACK button on ALV is taking to a blank screen (whose Program(GUI) = SAPMSSY0 & GUI status = STLI).

SKIP statement on selection-screen causes a NEW-LINE written(WRITE statement) in program SAPMSSY0, put a break point at FORM new-line & debug BACK button to get a feel of it.

Remove SKIP from selection screen and try.

Hello,

Its possible that you are facing this problem because you might call avl function inside PAI Module. It causes a nested Calling of functions. First it calls the screen then the avl function. So when you back out it closes the avl function and displays you a blank screen. I solution i found is this;

  FORM disp_avl.
 SET PF-STATUS 'STATUS_0100'.
 SET TITLEBAR 'TITLE_0100'.



 SELECT * FROM zhr_t_customer3 INTO TABLE gt_customer3.

cl_salv_table=>factory(
  IMPORTING
    r_salv_table  = go_salv
   CHANGING
     t_table      = gt_customer3

    ).

go_salv->display( ).
    ENDFORM.

and then you need to call it outside the PAI module. like this;

SELECTION-SCREEN BEGIN OF BLOCK b11 WITH FRAME.
  PARAMETERS: rb_rapor RADIOBUTTON GROUP gr1,
              rb_entry  RADIOBUTTON GROUP gr1.
SELECTION-SCREEN END OF BLOCK b11.

START-OF-SELECTION.

IF rb_report = 'X'.
 PERFORM disp_avl.
   ENDIF.
  IF rb_entry = 'X'.
    CALL SCREEN '0200'.
  ENDIF.
