Measure Difference Between Cumulative Measure

pbijack93 — Wed, 22 May 2024 13:12:31 GMT

I have created the following code

FTE_Prev_Mnth = CALCULATE( [FTE_Demand], PREVIOUSMONTH(Date_Dim[Date]) , Date_Dim[Date] <= MAX(Date_Dim[Date]) )

Which then goes into

FTE_Mnth_Var = CALCULATE([FTE_Demand] - [FTE_Prev_Mnth] )

The output is:

Year	Month	FTE_Demand	FTE_Mnth_Var
2024	May	626.5572	1.773035
2024	June	625.0259	-1.53131
2024	July	648.6083	23.58244
2024	August	655.1697	6.561367
2024	September	655.0414	-0.12826
2024	October	676.5294	21.48798
2024	November	684.7248	8.195445
2024	December	689.8698	5.145005
2025	January	668.7971	-21.0728
2025	February	675.9296	7.132578
2025	March	685.1627	9.233071
2025	April	691.6453	6.482635
2025	May	629.0432	-62.6022
2025	June	631.6405	2.597319
2025	July	613.5211	-18.1194
2025	August	616.9264	3.405306

How can i add the different months of FTE_Mnth_Var together bearing in mind they are a measure and not calculated column - i want to see the difference between for example june 2024 & March 2025 using my Date_Dim Table. Also the 1.77 showing in May 2024 shouldnt be showing amonth variance if that month isnt visible?

Thank you

Jack

Hi,pbijack93

Regarding the issue you raised, my solution is as follows:

1.First I have created the following table and the column names and data are the data you have given:

2. First of all, about your line value does not exist will not be counted, I recommend that you use the ISBLANK () function, his role is to first determine whether the value is empty, it is recommended that you can modify your measure to the following code:

TE_Mnth_Var= IF( ISBLANK([FTE_Prev_Mnth]), BLANK(), [FTE_Demand] - [FTE_Prev_Mnth] )

Here is the relevant documentation:
ISBLANK function (DAX) - DAX | Microsoft Learn

3.Secondly, if you want to count the values in the date interval you set (the values come from a measure), you can also use the Sumx() function, here is the measure I created to meet your needs:

Measure = SUMX('Date_Dim',CALCULATE([FTE_Mnth_Var],FILTER('Date_Dim','Date_Dim'[Date]>DATE(2024,6,1)&&'Date_Dim'[Date]<DATE(2025,3,1))))

Here is the documentation for it：

SUMX function (DAX) - DAX | Microsoft Learn

Can you share sample data and sample output in tabular format if I am misunderstanding? Or a sample pbix after removing sensitive data. We can better understand the problem and help you.
