In my requirement I made two columns as primary and I've loaded the data by FM and one column getting unique values and the other column getting duplicate values.

Hello,

The combination of the two columns is the one that is unique.

choosing two column as primary key means the combination of the two column is unique, doesn't mean each column individually is unique.
