get a distinct list from expression results

[spikenaylor1]

I have a list of people, for each person I have a % expression in this for documents correct. 

I end up with the list of people with the expression result ranging from 0% to 100%

I am interested in seeing all the peoples results, but then being able to filter the ones with 100%

How can I generate a list showing the distinct % results so when selecting the 100% in the list it filters out all those who have not reached 100%

my expression for the % is

num(Count({<RFT = {'YES'}>} RFT)/Count(Document),'.%')     Label - RFT

regards

May be create a list box object with this expression

Aggr(
    Only({1<Person = {"Count({1<RFT = {'YES'}>} RFT)/Count({1} Document) = 1"}>} Person)
, Person)
