Remove Duplicates

Hi All,

In my requirement ,i need to delete all the repeated entries and show only the entries which r not repeated.

For eg : IT_output has values like 1, 1, 2, 2, 2, 11, 12, 16 , 16.

IT_final should show only values like 11, 12 only.

Can anybody let me know the syntax to implement this logic.

Regards

Rohini.
