Need Help - Searching and Comparing a String

I am having a little bit of an issue. I need to compare a string in one column to another, then provide the string in another column. The problem is I have to search the entire column and will not be a 1:1 match.

 

Column AColumn BColumn CColumn D
  ABCXYZ
ABCXYZ  
DDCTTV  
  DDCTTV
    

 

In the example above, I want to search Column A where it matches Column C, and then provide output of Column B in Column D

 

I appreciate anyone's help. 

 

Thanks,

J

Hi @v-tangjie-msft,

 

First I'd like to thank you for your help. When I use your formula I receive "A circular dependency was detected". I think this is because I did not state in my example above that value can be had more than once. Example below:

 

Column AColumn BColumn CColumn DColumn E
  ABCXYZBusiness Unit 1
ABCXYZ  Business Unit 2
DDCTTV  Business Unit 3
  DDCTTVBusiness Unit 4
  ABCXYZBusiness Unit 5
ABCXYZ  Business Unit 6
  DDCDDCBusiness Unit 7

Hi @jj101 ,

 

According to your description, here are my steps you can follow as a solution.

(1) My test data is the same as yours.

(2) We can create a calculated column.

Column D =
VAR MatchedRow =
    CALCULATE (
        MIN ( 'Table'[Column B] ),
        FILTER ( 'Table', 'Table'[Column A] = EARLIER ( 'Table'[Column C] ) )
    )
RETURN
    IF ( NOT ISBLANK ( MatchedRow ), MatchedRow, BLANK () )

(3) Then the result is as follows.

If the above one can't help you get the desired result, please provide some sample data in your tables (exclude sensitive data) with Text format and your expected result with backend logic and special examples. It is better if you can share a simplified pbix file. Thank you.

 

Best Regards,

Neeko Tang
