Search Help to populate field

Question

Hie guys,
As a work around to my clients request i have modified an elementary search help in transaction CV02N. Instead of showing customers under the Obect Links i am showing the business partners. however when the desired business partner is selected i want to populate the adjacent description field with the full name of the business partner as would have appeared in the search help.
how can i populate that field??
regards
Isaac Prince
