clear buffer record from table view

Hi all,

I have added one new custom view as new assignment block in opportunity . I am entering the data into view ,  but here scenario is with out saving the record I am cliking on CANCEL button in Header. when I open the same opportunity from recent items , entered record is still appearing in table view .

When I click on cancel, i need to remove that buffering record from view . How can i do that.

Already i tried using the method WD_DISTROY method , but it is not clearing that buffering record.

Regards,
