Return Data For 6 Months Within A Time Period

[Anonymous]

Hi,

If I want to return true if a person has won a has within 6 months of their whole time working at a job, how would I code this in Dax?

So for example, if User A has won a prize on 04/07/2020 and another prize on 05/10/2020 and worked at the company from 01/01/2020 (Start date) to 15/12/2020 (End date), how would I set a date filter to find if the user has won two prizes within 6 months of their start date and end date?

User	Prize Date	Start Date	End Date	Prize
A	04/07/2020	01/01/2020	15/12/2020	1
A	05/10/2020	01/01/2020	15/12/2020	1

 This is the example table. The Prize Count should show 1 after adding a measure using dax as User A has won two prizes in 6 months.

This is what I have so far:

(Users is the Table Name)

Prize Count = CALCULATE( SUM(Users[Prize])>1

When I create a table with User ID and Prize Count it shows me the correct count, but now I need to add that date filter to check between their dates of employment to see if in a 6 month period, they've had more than 1 prize.

Hi @Anonymous ,

15/12/2020 is definitely December 15th, so 04/07/2020 and 05/10/2020 are July 4th and October 5th, right?

If it is, it does not meet the condition you said to be awarded within six months(Start date is 1/1/2020, so max date is 7/1/2020). Then 04/07/2020 and 05/10/2020 will return false.

Please correct me if I'm wrong.

Best Regards,

@Anonymous , Try measure like

//Date1 is independent Date table
new measure Users Won =
var _max = maxx(allselected(Date1),Date1[Date]) // Or use Today
var _min = eomonth(_max, -6) +1
return
calculate( distinctCOUNT(Table[User]), filter('Table', 'Table'[Prize Date] >=_min && 'Table'[Prize Date] <=_max && Table[Start Date]<= _max && Table[End date] >= _min))

or

//Date1 is independent Date table
new measure Prize Won =
var _max = maxx(allselected(Date1),Date1[Date]) // Or use Today
var _min = eomonth(_max, -6) +1
return
calculate( COUNT(Table[User]), filter('Table', 'Table'[Prize Date] >=_min && 'Table'[Prize Date] <=_max && Table[Start Date]<= _max && Table[End date] >= _min))
