hi,
pass your search help name there so that your desired search help ll come there..
use this,
i_value_help_type = if_wd_value_help_handler=>CO_PREFIX_SEARCHHELP
if you want standard SH means comment this stmt,
if you dont want SH means,
use tis,
i_value_help_type = if_wd_value_help_handler=>CO_PREFIX_NONE
hope this helps,
Mathan R.
