Measure for Start and End Dates - Days Assigned Graph

[draxicle1]

Dear PBI community,

I have a Power Bi Measure question which I have seen called the “Events in Progress” problem. I've researched and tried to adapt various solutions I've found on this, but none quite fit my scenario. I am fairly new to Power BI and DAX so would appreciate any responses.

(This is a simplified version of my real world problem)

I have a table called P6_Planned, which is a list of activities, and a separate date table called CalendarTable.

P6_Planned contains columns called Activities (a line item name), Start (date), Finish (date), and a sum of Days Assigned (Finish - start +1). The dates are connected to the CalendarTable.

I am trying to create a measure that looks at a date and sums all the Days Assigned across ALL the activities, and takes into account the cumulative effect of overlaps. With this measure I would like to plot a graph with x-axis being dates and y-axis showing how many assigned days there are across all activities

I have a attached an illustration of what I’m trying to achieve. (Not sure how to attach the pbix file to this post.)

Thanks in anticipation!

Hi @draxicle1 

Try the following measure

Measure = 
SUMX(
    CalendarTable,
    CALCULATE(
        COUNTROWS(P6_Planned),
        FILTER(
            P6_Planned,
            P6_Planned[Start] <= CalendarTable[Date]
            && P6_Planned[Finish] >= CalendarTable[Date]
        )
    )
)

This is the result you want

Best Regards,

This is great. Thank you so much for your time. I have replicated this is my main model.

The only fly in the ointment (I learned from a recent meeting) is that I made the assumption that every day between the start and finish is actively being used on every activity in the list. Apparently there will be a new column that shows the amount of time (effort in hours)  used between those dates.  So I guess if you had 10 days duration, but only 24 hours of actual effort spread across those, you would have an average 2.4 hours showing every day.

Perhaps that's one for another post.

Thanks all the same.
