Sum of Occupation Days per Resource in given Month

[Anonymous]

Dear Community,

I am struggling with a formula for the Occupation of Resources per Month.

My current formula:

Occupied Days WithIn Month =

VAR StartDate = VALUE( SELECTEDVALUE( 'Resource Assignments'[Start] ) )

VAR FinishDate = VALUE( SELECTEDVALUE( 'Resource Assignments'[Finish] ) )

VAR MinDateInContext = VALUE( MIN( 'Calendar'[Date] ) )

VAR MaxDateInContext = VALUE( MAX( 'Calendar'[Date] ) )

RETURN

IF( AND( StartDate < MinDateInContext, FinishDate > MinDateInContext ) ,

        MIN( FinishDate, MaxDateInContext ) - MinDateInContext,

            IF( AND( AND( StartDate > MinDateInContext, StartDate < MaxDateInContext ), FinishDate > MinDateInContext ),

                 MIN( FinishDate, MaxDateInContext ) - StartDate,

                    BLANK() ) )

This basically gives me the right thing, I only need to add something to finalize it. My Matrix visual looks like this:

*All numbers of days and dates are used as examples

Resource     - Jan 23 - Feb 23 - Mar 23

Resource A      5 days

Resource B                   10 days

Problem A) is this formula doesn't calculate the SUM of Occupation Days per Resource, so when a Resource works on task 1 for the first 5 days of January and also works on task 2 the last 5 days of January, the formula gives 5 Occupation days, but ofcourse I need 10.

Problem B) is that this formula doesn't work when a Resource works on task 1 the last 10 days of January until the 10th day of February. In this case the formula should give 10 Occupation days in Jan and also 10 in Feb (in the Matrix visual), but instead the formula gives the 10 of Jan and skips the 10 in Feb as a whole.

Hopefully you can grasp my situation here. If not clear, I will come back with a sample file.

All best,

Fabian

Hello,

I created this little sample table. My actual data is imported and synced to Project for the Web. 

Resource	Start	Finish	Task	Occupied Days
Resource A	2/1/2023	13/1/23	Task A	10
Resource B	9/1/2023	3/2/2023	Task B	20
Resource A	23/1/23	27/1/23	Task C	5

What I need is a matrix view that looks like the following:

Resource	Jan'23	Feb'23	Mar'23
Resource A	15
Resource B	17	3

The value numbers represent the amount of days a resource is occupied in total (tasks combined), calculated per month.

In my formula mentioned in the first message it would give value 10 days in Jan 23 for Resource A, and not calculate the sum (=15). For Resource B it would give only the 17 in Jan 23 and does not calculate the days that are in the next month due to overlap.

Any ideas how to fix this?

Best,

Fabian
