select options: Restricting Value Display in Search Help Parameters

Hello friends,

I have following requirement.

I have declared one select option. On that select options I'am having different search help paremeters on which I can restrict the search help values display.

Can I specify the restriction in search help at the time of programming so that it would display only the values that follows the given restriction?

I can ofcourse do this by AT SELECTION-SCREEN ON VALUE REQUEST, however I am trying to avoid this.

How can I proceed?

Points will be rewarded generously.

Best Regards,

Navin
