hI,

I want to get the checkbox displayed but am unable to do so.I have done what is suggested as in code below:

" For checkbox

insert initial line into table ch_fieldcat assigning <wa_catalogue>.

<wa_catalogue>-col_pos = lines( ch_fieldcat ).

<wa_catalogue>-row_pos = 0.

<wa_catalogue>-fieldname = 'CHECKBOX'.

<wa_catalogue>-inttype = 'C'.

<wa_catalogue>-edit = 'X'.

<wa_catalogue>-seltext =

<wa_catalogue>-coltext = 'Choose test class for tagging'.

<wa_catalogue>-checkbox = abap_true.

<wa_catalogue>-outputlen = 10.

call function 'LVC_FIELDCATALOG_MERGE'

exporting

i_structure_name = im_structure_name

changing

ct_fieldcat = ch_fieldcat

exceptions

others = 1.

if sy-subrc <> 0.

raise exception type cx_pak_gui_error.

endif.

describe table ch_fieldcat lines l_lin.

loop at ch_fieldcat assigning <lfs_field>.

case <lfs_field>-fieldname.

when 'SOBJ_NAME'.

<lfs_field>-coltext = 'Test Class'(002).

<lfs_field>-outputlen = 30.

<lfs_field>-key = 'X'.

when 'CHECKBOX'.

<lfs_field>-coltext = 'Choose TestClass for Tagging'(003).

<lfs_field>-outputlen = 30.

<lfs_field>-row_pos = 0.

<lfs_field>-key = 'X'.

when l_fieldname. " ICON*

<lfs_field>-icon = abap_true.

<lfs_field>-no_out = 'X'.

when others.

<lfs_field>-key = 'X'.

<lfs_field>-no_out = 'X'.

endcase.

endloop.

call function 'LVC_FIELDCATALOG_MERGE'

exporting

i_structure_name = im_structure_name

changing

ct_fieldcat = ch_fieldcat

exceptions

others = 1.

Please advise.

Refer this sample program <b>BCALV_EDIT_05</b>

Hi,

To output a column with checkbox,you need to code like below in fieldcat.

DATA: i_fieldcat TYPE slis_t_fieldcat_alv.

DATA: line_fieldcat TYPE slis_fieldcat_alv.

CLEAR line_fieldcat.

line_fieldcat-fieldname = 'CHK'.

line_fieldcat-tabname = 'I_DATA'.

line_fieldcat-seltext_l = 'Checkbox'.

line_fieldcat-checkbox = 'X'. " Display this field as a checkbox

line_fieldcat-edit = 'X'. " This option ensures that you can

" edit the checkbox. Else it will

" be protected.

APPEND line_fieldcat TO i_fieldcat.

But I don't think you can selectively enable some rows to check the checkbox.

Kindly reward points if it helps.
