problem with value table

Hi Experts,

  i am modifying module pool program in that i found, one field displays the search help values based on the value table maintained at domain level.

As per requirement i have changed the value table name maintained at the domain level. Even i changed the value table..still the search help values taken from old value table instead of new value table..how can avoid this situation..how to provide the search help values based on new value table?
