Update Itab flag using ALV Grid

Former Member — Wed, 08 Jun 2011 20:08:50 GMT

hi experts,

can you help me with this. i created a report that generates data from pa2006 using alv grid display then i added checkbox on the display. what i want is when i tick the checkbox it should modify the itab-flag field = 'X'. So that when i call the Delete command only data with flag='X' should be deleted in the itab and in pa2006.

here my source sode.

Any specific reason to go for the selected rows with "get_selected_rows" instead of the existing flag variable? Any how in your code the index is not properly passed,


DELETE it_pa2006 INDEX lt_index.

Should be...


DELETE it_pa2006 INDEX lt_index-index.

put this method CALL METHOD g_grid->refresh_table_display after endloop.

Hi,

I think you need to double click on row once you checked it to refresh values.

Try this.

Add the following to t_layout before CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY':

t_layout-box_fieldname = 'FLAG'.

In Form User_command in your loop at it_pa2006 check the flag as follows:

if gs_pa2006-flag = 'X'.

The marked lines will have 'X' in FLAG.

Your GUI_STATUS should be a copy of STANDARD_FULLSCREEN (FG SLVC_FULLSCREEN) and contain Pushbutton 'DELETE'.

I copied your coding and modified it as detailed above - it worked okay. gs_pa2006-flag was filled for all the marked rows.

Re: Update Itab flag using ALV Grid

Sorry, I overlooked that I also removed the following line of code, as it caused problems:


l_fieldcat-checkbox = p_chk.

l_fieldcat-checkbox should not be filled.

Hope this helps.

I did the below mentioned changes in your code and the flag variable got 'X' when checked.

Commented the box fieldname assignment.


*t_layout-box_fieldname = 'FLAG'.

and added the grid settings and passed to ALV


  data lv_s_glay TYPE  LVC_S_GLAY.
  lv_s_glay-EDT_CLL_CB = 'X'.
  CALL FUNCTION 'REUSE_ALV_GRID_DISPLAY'
    EXPORTING
...
      I_GRID_SETTINGS        = lv_S_GLAY
....
