Counting Value Based On It's Last Appearence

Ok, I found the solution. 

1. Create table by Person ID, Calendar Date and the distinct count of the person ID. Then removing the filter context from the calendar date and the sorting column in the calendar table:

2. Grouped the table from step 1 by person id, while interating the group to get the last date (MAXX). And then selecting only the column with the latest date:

3. Then if the calendar date = the date found in step 2 return me the distinct count of the person id where the calendar date = last calendar date:

The result is exactly what I was looking for:

Thank you all for your help and suggestions. Hope this might help to you as well!

Have a nice day and great weekend,
