Help required in the Calculated Dimension

[qlikviewforum]

Against each date(MM/DD/YYYY) i have month value as (YYYYMM). Since I am not using the date in the dimension it is showing duplicate value which is same as many dates in the month. So to avoid this duplication i want to get rid of the duplicates in the dimension. Please help me to write the calculated expression for the same.
