How to use the CASE statement in Power BI?

Hi,

 

1) How do I convert the below CASE statement to DAX in Power BI? 

 

case when cCount > 0 and ThreeYrAvg > 0
then
case
when cCount - ThreeYrAvg >= 5
and round( ( ( cCount * 1.00 - ThreeYrAvg ) / ThreeYrAvg) * 100, 2 ) >= 10.00
then 'Increase'
when cCount - ThreeYrAvg <= -5
and round( ( ( cCount * 1.00 - ThreeYrAvg ) / ThreeYrAvg ) * 100, 2 ) <= -10.00
then 'Decrease'
else 'None' end
else 'None'
end "Notable Change?",

 

Column 1 = cCount

Column 2 = ThreeYrAvg from Table A.

 

I want to create a calculated 'Column' named = "Notable Change?" which will have Increase, Decrease and None values in the new column (from the CASE statement).

 

2) and then a calculated 'Measure'. Calculated 'Measure' should show just the record count of "Increase and Decrease" which I then show it using a 'Card' visualization.


Do I need to use 'Switch' DAX expression?

 

Appreciate your inputs!

HI @BBIUser,

I've created a sample data and used custom column to use -IF-ELSE-IF statements to get the result you need as shown below in images.

Thanks @Anonymous! It works.

 

Since I am new to Power BI and only trying out POCs, it is good to know that there is an option 'Custom Column'.

But can I know in what scenarios the 'custom column' and 'calculated column' should be used?

 

Thanks again!

Yes, SWITCH funtion is your equivalent or nested IF statements. Give me some sample data to play with and can be more specific. Please see this post regarding How to Get Your Question Answered Quickly: https://community.powerbi.com/t5/Community-Blog/How-to-Get-Your-Question-Answered-Quickly/ba-p/38490

DAX is easy, CALCULATE makes DAX hard...



@Greg_Deckler My apologizes if my question was not clear and for not posting the sample data.

Here is the sample data.    

 2018-05-04_1500.png

Here cCount is "Current Year",
pCount is "Prior Year",
p1Count is "Current Year-2",
p2Count is "CurrentYear-3"

ThreeYrAvg is "3 Year Avg"

 

With the CASE statement I want to add another calculated column and a measure. Please let me know if it is more clear with the sample data. Thanks for your help!
