I have a promised hours calculation that looks at two dates (Coalesce) and gets the number of weeks in the month and then multiply it by the max promised hours for an employee which has a row for every week of the month. The employee could have 5 rows for every entry a week and the promised hours shows up the same as for example 40 for that week, thus why I have to take the max instead of do a sum. But at the end I need to show the total number of promised hours per week for whatever timeframe is chosen in the date slicer per employee.
Promised Hours Calc = CALCULATE(WEEKNUM(Max([CoalesceActualStart_AbsenceStart]),1)-WEEKNUM(MIN([CoalesceActualStart_AbsenceStart]),1))*MAX(FSLData[PromisedHours])
I then need it to do a sum for every employee on the above calculation.
I am getting all sorts of errors trying to do a sum on the calculation as a whole.
What you write is confusing and incomprehensible. That's why you get the errors. As soon as you are able to formulate your problem in such a way that others can understand it, you will understand it yourself and the errors will go away.

I have a calculation where I need to divide the budget by 12 and then multiply by the number of months passed not including this month.
So for this month, I have DIVIDE([GP Budget $],12)*4. But I obviously don't want to have to change the calculation every month. My calendar table has a month number so I was hoping to return that value depending on what the previous month is. I'm sure there are about a thousand ways to do this but I'm still new to BI and my Bing searches are failing me.
So, strange one to explain...
I have a table with the start dates of each person in project (each start day is the first Monday of the week)
I want to know how many people were in the project on any given week.
If I select two weeks in a slicer, for example
Week1
Week3
And there were 10 people in week 1 and 30 in week 3 the total should be 40.
How do I build a measure to do this.
Essentially I'm asking it to count the number of rows(project members) where the start date is >= each selected date and sum each individual result.
I hope this has made sense unable to share much due to work red tape
Thanks

I would do this in the following way:
Create a bin for the work week
Create a measure to count the bin from step 1.
I am trying to create a power BI calculation as an average per day of how many times a code was tripped. The dax calculcation that I have
Count Trips average per Day =
AVERAGEX(
KEEPFILTERS(VALUES('ruledata (2)'[Date].[Day])),
CALCULATE([Count Trips])
)
works fine when the average is being calculated over a couple days. I double checked this by hand and can confirm that it is accurate until at least 2 weeks. However once the time range increases to include months the average starts getting ridiculous and begins displaying average trips /day values that are much higher than the highest number of trips on a single day. I have confirmed that the data in the graph is correct
So I know that the values should reflect what is in the graph. In this two month example the DAX formula calculated the average to be 149.03 but the actual average/day should have been 82.8.
In general is there some sort of error in the DAX formula that I am using that could cause this?
I guess that 'ruledata (2)'[Date].[Day] is the day of the month. So if you take the average it will be wrong because when you take the average of e.g. March and April you will divide the total trips by 31, and not by 61 (30+31). So use 'ruledata (2)'[Date].[Date] instead.
I need to find one way or another the following formula in Power BI:
Total Hours of Use of a Machine = Hours Function * Range of Functioning
where Hours Function is the hours of use of a certain machine. Take it at a cost that for each machine is a constant and Range of Functioning is the difference between the final date of the evaluation and the initial date, measured in hours.
For example, I want to measure the Total Hour Use of a Machine in between 15/10/2019 and 14/20/2019. So the math is the following:
Assume: 2 machines
Hours Function machine A: 6
Hours Function machine B: 9
Range of Functioning = 15/10/2019 - 14/10/2019 = 24 hours
The output:
Total Hours of Use of a Machine A: 144
Total Hours of Use of a Machine B: 216
I need to do that in Power BI in a way that any user moving a slicer of date, refresh the Total Hours of Use of a Machine.
I don't find any way that I can get the difference between the final date of the evaluation and the initial date and put in DAX or a new column.
You have to use measures if you want to recalculate the value when you change the date with a slicer.
The first step is to be sure to be able to calculate the number of day selected by your slicer.
It seems to be easy but if you use the function FirstDate on your calendar table directly integrated in PowerBI.
You'll never have what you expect.
The tricks here to get this number of day is to calculate the number of rows in your calendar table with the function countrows.
When you have this number day you just have to multiply this by 24 ( hours) and by the sum of your "Hours Function machine".( 6 for A 9 for B in your example )
( It's important to use the sum or another aggregate function like average because if you have multiple value the measure fall in error because it need only one value to multiply).
The dax formula looks like :
= COUNTROWS(('Calendar')) * Sum(Machine[Hours function])
You can then display this measure filtered by the Machine Name and a date slicer(based on your calendar table).
In Power Bi my average matters per day is not stopping on the current day.
Avg Per Day = DIVIDE([Matters],SUM(Dates[IsWorkday]))
where IsWorkday = IF(ISBLANK(Dates[Holiday]),IF(Dates[DayOfWeekNumber]>1&&Dates[DayOfWeekNumber]<7,1,0),0)
and Matters = COUNT(BillingData[Item])
So today is the 27th of the month so 18 of 20 work days are completed for the
month. So need [matters]/18, not [matters]/20.
How do I factor that in to my average and not affect previous months.
Any help appreciated.
Sounds like you need to just add one more condition to your if statement to add in that the date is less than todays date. Check out this post. I think it might have the solution to your problem or at least give you the idea you need to solve the issue.
