thanks a lot for your reply. when I gave Sysdate as parameter , it opens calendar and I can select anydate.
I have four date fields created_date_to, created_date_from, processed_date_to,processed_date_from
date_lov.get_date ( sysdate,
                    'search.CREATED_TO_DATE',
                    0,
                    0,
                    'Date List of Values',
                    'OK',
                    'Cancel',
                    TRUE,
                    FALSE,
                    FALSE);How do i change formatmask for created_to_date so that it also works as a paramter.
