start date - end date and sum per month

fsim — Wed, 09 Mar 2022 16:28:36 GMT

Hi !
I'm not even sure how to express myself on this problem.

I have one table of tasks, with a start date, an end date, a number of allocated daily hours and an user.
I also have a calendar table.

I want to have an idea of the montly occupation rate of my users knowing that they are supposed to work 8h/day from mon to fri.

I guess I should create some measure that counts for every project/user the number of days between the two dates , then multiply by the number of allocated hours and sum the results on a monthly basis. Then devided by the numbers of avalaible working hours. (I already have this one !)
So a specific user, working 4hours a day on one single project that ran from feb 1st to March 1st should have a 50% occupation rate for february and 2% on March (4h/ 23 working day * 8h)
I tried using datebetween , but I get an error message saying that there are many different start date. I can't figure it out (spent too much time in power query and not enough on Dax :-D)
Could a good soul gives me an hint ?
thanks in advance

Hi Liang,
thanks for your answer.

Obvioulsy, Dax is not the best tool for this. I decided to go back to PowerQuerry and generate a list of date for each reccord. Then I was able to expand the list in new rows.
List.Dates([start_date],Duration.Days([end_date]-[start_date])+1, #duration(1,0,0,0))
Now I have to deal with repeated dates, but this is another storry
