Problem in finding a data while using mandatory

Hi,

I have a problem while finding a data while using mandatory. For example if i have 4 fields in the header form i set all the 4 fields as mandatory it will check while we press the add button. For finding the record browse by itemcode means i ll give the itemcode in find mode and press the find button but other 3 fields are null so its passing the mandatory validation message for other fields. How to solve this problem.
