Difference of Measure - Alternate Solution

[jayasurya_prud]

Hi, I am working on a dashboard, where I am using cards visuals. Like below

In the card, C = A-B. 

Now, I am facing the scenerio in which based on the filters, sometimes the value of B will blank() which I will be replacing by 0. 

In that case of B comes as Blank() (replaced by 0), the C should not come as C = A -B. Like A = 10, B = Blank()/0, C = 10. 

In those cas, the C should indicate NA. 

I know that I can use if condition. But since I am using if condition already in B to replace blabk() with 0, I am not sure hoe to get this. 

Please help.

Thanks!

Hi @jayasurya_prud 

>>But since I am using if condition already in B to replace blabk() with 0, I am not sure hoe to get this. 

please try this, 

measure1= if(isblank([measure in card B]),0,[measure in card B])

and put measure1 into Card B

measure2= if(isblank([measure in card B]), "NA", [measure in card B])

and put measure2 into Card C

@jayasurya_prud , Not very clear

but you need like

c = if([b]=0 || isblank([b]) , blank(), [A] -[b])
