How to make checkbox to be pre-selected in ALV

[Rampa]

Hi all,

I'm creating ALV report and I want to create checkbox in the first column of the row. So I have a field SEL(1) in my structure and I`ve made the fieldcat:

gs_fcat-col_pos = 5.
  gs_fcat-coltext = 'Check'.
  gs_fcat-fieldname = 'SEL'.
  gs_fcat-tabname = 'GT_TREE9001'.
  gs_fcat-outputlen = 10.
  gs_fcat-checkbox = 'X'.
  gs_fcat-edit = 'X'.

That works, checkbox is displayed.
But now I need to make all the checkboxes to be checked for the first start of my program.
I mean when user executes my report all the checkboxes must be checked by default.

I have tried to do following:

loop at gt_tree9001.
gs_tree9001-sel = 'X'.
modify gt_tree9001 from gs_tree9001.
endloop.

But it doesnt work, I now see checkbox and mark 'X' near but not the checked ckeckbox.

Any help will be appreciated.

Thanks in advance,
Rampa

Hello Rampa,

loop at gt_tree9001.
gs_tree9001-sel = 'X'.
modify gt_tree9001 from gs_tree9001.
endloop.

Change code:

loop at gt_tree9001 INTO gs_tree9001.
gs_tree9001-sel = 'X'.
modify gt_tree9001 from gs_tree9001 TRANSPORTING sel.
endloop.

Hi Rampa,

Use the below logic.

Declare a field symbol with respect to your local structure internal table.

field-symbols : <wa_ekko> like LINE OF it_ekko.

Before displaying ALV fm write this code.

loop at it_ekko ASSIGNING <wa_ekko> .
<wa_ekko>-check = 'X'.
MODIFY TABLE it_ekko FROM <wa_ekko> TRANSPORTING check.
ENDLOOP.
