Hi Team,
I have fact table and 2 dimension table called the months table. The months and the raw data are NOT connected to each other
.Here I am trying to compare the month against the month. In the below snapshot, I am trying to compare Feb against Mar to see what fruits have newly come in Mar when compared to Feb.
I was able to do this logic in the Calculated Table, however, i wanted this calculation to be a dynamic measure. because i wanted a dynamic comparison of two months of data.
Below is the Dax measure I have used, which is not giving me the correct result
The Flag should have populated as "Yes" for Peach in Mar because we are comparing Feb to Mar and only "Peach" is the new fruit showing in Mar. The rest of the records should be populated as "No".
Kindly help with the logic.
Thanks and regards,
Vijay Krishnan

Hi @anvikuttu
Try to modify the way in which you use the EXCEPT function. I haven't tested the below but give it a go and modify to your needs:
New Fruits Flag =
VAR SlicerMonth1 = SELECTEDVALUE( Month_Table_1[Month] )
VAR SlicerMonth2 = SELECTEDVALUE( Month_Table_2[Month] )
VAR FruitsInMonth1 =
CALCULATETABLE (
VALUES( Raw_Data[Fruits] ) ,
Raw_Data[Month] = SlicerMonth1
)
VAR FruitsInMonth2 =
CALCULATETABLE(
VALUES( Raw_Data[Fruits] ) ,
Raw_Data[Month] = SlicerMonth2
)
VAR NewFruitsInMonth2 = EXCEPT ( FruitsInMonth2 , FruitsInMonth1 )
VAR CurrentFruit = SELECTEDVALUE ( Raw_Data[Fruits] )
RETURN
IF (
CurrentFruit IN NewFruitsInMonth2 ,
"Yes", "No"
)
Make sure to place this measure in the visual where you have the fruits listed down and it should dynamically show "Yes" for new fruits in the selected comparison months.
Hoping this helps mate.

Thank you @TheoC for your quick reply. Your code partly fixes the problem.
The resultant dataset should be based on Month2. If you see below (snapshot) first thing is we are trying to see what fruits are available in Month2 which is not available in Month1. The flags populated for Feb is correct,
however we also see that there is flag = Yes for Mar as well which is incorrect.
I have slightly modified your code
Hi @anvikuttu
Are you able to send me the sample data you're working with (or the PBIX file)?
Also, I just realised that the Month1 and Month2 tables are not necessarily structured in a particular order of month (i.e. Month1 = Feb, Jan, Mar & Month2 the same).
Let me know if it's possible to send through the data!
Thanks heaps,
Theo

Hi @TheoC , the modified code that I pasted previously is working fine. Moreover, I do not find the option to attach a pbix file here. I have also accepted your code as a solution.
Thanks for all your help...appreciate it.
Thanks and regards
@anvikuttu no worries. If at all you need further guidance, feel free to add me on LinkedIn and then send the PBIX. More than happy to assist however I can mate.
