ALV grid not updating the correct value in the internal table

[Former Member]

hi all,

I have searched this question in the SDN but I am not getting a clear answer. SO need helping hand from the expert.

I am using a ALV grid and in the toolbar there is a button " CHANGEREP" which display another ALV grid based on the date entered in the pop-up window.

in the first time when I clicked this button, the value displayed correctly then I change new date and click the button again, the old value is displayed in the ALV grid.

I checked in debugging mode , ts_output is getting updated but not displayed correctly in the ALV grid.

please find the piece of code

MODULE status_1002 OUTPUT.

  DATA : gr_event_handler2 TYPE REF TO lcl_event_handler .

  SET PF-STATUS 'Z_ALV2'.

* Create Container the first time Only

*  IF NOT g_custom_container2 IS INITIAL.
*    EXIT.
*  ENDIF.

* Create CONTAINER & GRID for ALV


    CREATE OBJECT g_custom_container2
      EXPORTING
        container_name = g_container2.

    CREATE OBJECT grid2
      EXPORTING
        i_parent = g_custom_container2.



    CALL METHOD grid2->set_table_for_first_display
      EXPORTING
        is_layout            = ga_layout
        it_toolbar_excluding = ty_exclude
      CHANGING
        it_outtab            = ts_output
        it_fieldcatalog      = gt_fieldcat[].

    CALL METHOD grid2->refresh_table_display.


ENDMODULE.                    "status_1002 OUTPUT


MODULE user_command_1002 INPUT.

  CASE sy-ucomm.

* For EXIT, CANCEL,BACK

    WHEN 'EXIT'   OR
         'BACK'   OR
         'CANCEL' OR
         '&F03'.

      CLEAR : gt_fieldcat[],
              ty_exclude[],
              ts_output[].

      FREE grid2.


      LEAVE TO SCREEN 0.

  ENDCASE.


ENDMODULE.                    "user_command_1002 INPUT

Hi,

Free Container also.

I mean,

R_cont->free().

MODULE status_1002 OUTPUT.
 
  DATA : gr_event_handler2 TYPE REF TO lcl_event_handler .
 
  SET PF-STATUS 'Z_ALV2'.
 
* Create Container the first time Only
 
*  IF NOT g_custom_container2 IS INITIAL.
*    EXIT.
*  ENDIF.
 
* Create CONTAINER & GRID for ALV
 
 
    CREATE OBJECT g_custom_container2
      EXPORTING
        container_name = g_container2.
 
    CREATE OBJECT grid2
      EXPORTING
        i_parent = g_custom_container2.
 
 
 
    CALL METHOD grid2->set_table_for_first_display
      EXPORTING
        is_layout            = ga_layout
        it_toolbar_excluding = ty_exclude
      CHANGING
        it_outtab            = ts_output
        it_fieldcatalog      = gt_fieldcat[].
 
    CALL METHOD grid2->refresh_table_display.
 

ENDMODULE.                    "status_1002 OUTPUT
 
 
MODULE user_command_1002 INPUT.
 
  CASE sy-ucomm.
 
* For EXIT, CANCEL,BACK
 
    WHEN 'EXIT'   OR
         'BACK'   OR
         'CANCEL' OR
         '&F03'.
 
      CLEAR : gt_fieldcat[],
              ty_exclude[],
              ts_output[].
 
      FREE grid2.
 
 g_custom_container2->free( ). "add This statement
      LEAVE TO SCREEN 0.
 
  ENDCASE.
 
 
ENDMODULE.                    "user_command_1002 INPUT

Hi,

Can you tell me what code u have written for under CHANGEREP button.

Eg: MODULE user_command_screenno INPUT.

CASE sy-ucomm.

WHEN 'CHANGEREP'

Code.********

I think when u r clicking the same button it is not updating your corresponding table.

send me ur code for CHANGEREP button.

I guess, you should call the ALV Method refresh_table_display.

your_alv_object->refresh_table_display

exporting

is_stable = ls_s_stbl

exceptions

finished = 1

others = 2.

This method refreshs the ALV after e.g. a data change in your internal table. You don't need to destroy your ALV after a data update.

Martin
