## [dax] subtotal wrong - need help with context filter

Hello guys,

I have a matrix that shows wrong subtotals, I believe it's because of the context filters but I don't really get what I should change.

I have 2 tables : Calendar table & Fact table ( 1:* relationship on day )

My fact table contains the number of sales made hourly.

I'm trying to do a prediction with a rolling average, I created this measure :

2_months_prediction = CALCULATE(AVERAGEX(VALUES('Calendar'[WEEKS]),CALCULATE('FactTable'[NumberOfSales])),DATESINPERIOD('Calendar'[Date],max('Calendar'[Date])-7,-56,day))

And to compute the percentage of error I created this measure :
difference (%) = 1-DIVIDE([2_months_prediction],'FactTable'[NumberOfSales])

After that I wanted to count hourly ( and hierarchly daily weekly...) whether the prediction was good or bad, so i created these measures :
Good = COUNTROWS(FILTER(VALUES('FactTable'[Hour]),ABS([difference (%)])<=0.2))
% Good = Divide ( [Good], [Good]+[Bad])

If I don't use the week filter I get wrong results.
In the matrix, the numbers next to the name of the days are correct but if I move further down to hours I get wrong numbers, it is not correctly filtered.
The subtotal is also wrong.

Any idea on what am I doing wrong and how could I fix this?

Hi @KanisleS ,

Do you mean that when you drill down to hour level, you will get incorrect result from measure?  Is is part in screenshot incorrect? I couldn't see subtotal to this level in your screenshot. I think you can try

IF() and ISINSCOPE() function to calcualte in different hierarchy levels.

I think your calculate is based on your data model. Please share a sample file with me and show me a screenshot with the result you want. This will make it easier for me to find the solution.

I made a pbix sample file with randomized data : file

In the matrix with good/bad columns, if i drill down to hours and days the values are correct but the weekly values are wrong because they aren't the sum of the daily values, I want to fix that problem, the Total is also wrong since it doesn't compute the total sum of good/bad..

exemple week 2021s13 : Good should be equal to 10+7+11+12+9+13+11

I don't know where resides the problem, please let me know if you have an idea.

thanks!
