i want to find the duplicate records based on multple columns e.g. uniqueness on emp,dept,cat( apart from primary key) in details block. I want it at the entry level only instead of commit process.

I am not sure of what you mean' at entry' versus 'commit' process.

However, to retrieve only those records that are duplicated you can try something like the following in the 'where' clause:

emp, dept, cat in 
(select emp, dept,cat
   from tab
  group by emp, dept, cat
  having count(*) > 1)

This will give you the records for which there are duplicate entries. If you have two entries, delete one, and then requery, the singularly occurring record will not be displayed.

Use a when-validate-record trigger on your block to test whether the three fields have been used in a previous combination. If they have fail produce a message and fail the record.

You could also place a when-validate-item trigger on each field which tests if the three fields are populated (not null) and if so, test against the database.
