    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

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] )
VAR CurrentMonth= SELECTEDVALUE(Raw_Data[Month])

RETURN

IF (
    CurrentFruit IN NewFruitsInMonth2 &&  CurrentMonth = SlicerMonth2,
    "Yes", "No"
    )

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
