ECC6 - Refresh ALV grid

[Former Member]

Hi experts,

I have a dialog screen that will display a report in an ALV grid. I don't know what is wrong with my code. The ALV grid is not refreshed if I back out from the screen and go back in for the new data. It is displaying the data from the previous run. Please see code below.

Thanks,

Chuong

*** BEFORE THE ALV IS DISPLAYED ****

* create object
   CREATE OBJECT cust_contain_mass_ch_parm11
      EXPORTING container_name = 'CONTAINER_ALL'.

* create ALV grid
   CREATE OBJECT grid_mass_ch_parm11
        EXPORTING
          i_parent = cust_contain_mass_ch_parm11.


* Load data into the grid and display them
   CALL METHOD grid_mass_ch_parm11->set_table_for_first_display
    EXPORTING
              is_layout            = gs_layout_mass_ch
              it_toolbar_excluding = lt_exclude_mass_ch
    CHANGING  it_outtab            = itab_mass_ch
              it_fieldcatalog      = parm_fieldcat[] .


*** AFTER THE ALV IS DISPLAYED ****

       CALL METHOD cust_contain_mass_ch_parm11->free.
       CALL METHOD cl_gui_cfw=>flush.

Hi,

Use a vairiable first_flag , that is set for the first time as 'X' and only first time, u create controls and Set_Table_for_first_display function. and make first_flag as blank. and now call refresh_table_display.

char first_flag type c value 'X'.

if first_flag = 'X'.

• create object

CREATE OBJECT cust_contain_mass_ch_parm11

EXPORTING container_name = 'CONTAINER_ALL'.

• create ALV grid

CREATE OBJECT grid_mass_ch_parm11

EXPORTING

i_parent = cust_contain_mass_ch_parm11.

• Load data into the grid and display them

CALL METHOD grid_mass_ch_parm11->set_table_for_first_display

EXPORTING

is_layout = gs_layout_mass_ch

it_toolbar_excluding = lt_exclude_mass_ch

CHANGING it_outtab = itab_mass_ch

it_fieldcatalog = parm_fieldcat[] .

first_flag = ' '.

endif.

call function grid_mass_ch_parm11->refresh_table_display.

This should work.

Sheel.
