Set_table_for_first_display

Hi all,

Im having one ALV in my program using Set_table_for_first_display.

ls_layo-box_fname = 'FLAG'.

This is making the ALV with one Grid optiin by which I can choose the rows.

Now my problem is I want to choose only one row at a time...(not multiple rows)

I tried some values in the field selmode by

ls_layo-SEL_MODE = 'B'.

But no use.

can anyone give suggestion on this...

Thanks & Regards,

Sumithra
