Mark just one line in ALV

[former_member680493]

Hi everybody!

I'm doing an ALV (with FM REUSE_ALV_GRID_DISPLAY) that the user should mark just one line and click in a button to starting the process... But today the user can mark more than one line. I don't know how to configure just to mark just one line...

Can you help me???

Hi,

Check the number of lines selected and process further only if its equal to 1 else display an error message.

HI,

you check the number of lines selected by the user

if the user selects more then 1 line you can throw a error message

refresh gt_selected_rows.

call method vl31_grid->get_selected_rows

importing et_index_rows = gt_selected_rows.

*-- more than one line was marked

READ TABLE gt_selected_rows INDEX 2 TRANSPORTING NO FIELDS.

IF sy-subrc = 0.

MESSAGE s755(06).

EXIT.

ENDIF.

*-- nothing marked

READ TABLE gt_selected_rows INDEX 1 INTO wa_selected_rows.

IF sy-subrc <> 0.

MESSAGE s277(me).

Check the above example if the user selects more than one row throws a error message
