# Sum of distinct Count of Employees

How do I made a sum of a distinct count? For instance, if I want to sum up how many people were working on the 1st by the list of invoices, I would do a distinct count. What if I wanted to sum up all of those distinct counts for days 1-31?

Hi @Tblasz,

Distinct count works on a direct dimension. To perform distinct count by date, you would need to use distinctCountOver
syntax: distinctCountOver({Order ID},[{Order Date}],PRE_AGG)
details can be found here: distinctCountOver - Amazon QuickSight

Let us know if this resolves your issue.

Thanks,

How would I then sum up all the distinct counts?
With your example, lets say I wanted to sum distinct orders dates from Jan 4-7. It would be 12 but how do I write that in quicksight?

Iâ€™m sorry. Iâ€™m very new to this. I tried this formula but it didnâ€™t work.
sumOver(sum(distinct_count({employee},{transaction_date}>'12/01/2022)))
Iâ€™m trying to get a distinct count of the employees each day and then add all those values up for the month of December.

You canâ€™t put filter in the way that you have provided. You can select the visual and define the Filter criteria. Perhaps the below snapshot may help where you can define the filter. the syntax has to be like what I have shared in my expression.

I took out the dat portion so I can filter it how you showed but the equation still doesnâ€™t work.
sumOver(sum(distinct_count({employee},{transaction_date})))

Please reverify the syntax that you are putting. That {transaction_date} should be within a square bracket. Just like the below

Try to replace {Order ID} and {Order Date} respectively with employee and transaction_date
