Cross valiadation between two tables

[liapimentaa]

Hello!

I need help 😞

I have two tables. One with data with errors (let's call it table 1) (typos, mostly) and another with the correct information (table 2). I need to make a cross validation between the two tables, and when a value is table 1 is not on table 2, flag it (I tried with conditional formating, but it didn't work). 

Does anyone have any suggestions?

Thank you in advanced! 🙂

Hi @liapimentaa ，

If you need to check the upper and lower case of a word's letters, try a merge query in Power query:

then crate a new measure like:

Measure = IF(ISBLANK(COUNT(Table1[Column1.1])),"yellow")

and use it as a background condition:

If you don't need to check the case of letters, you can try this one:

Measure = 
VAR _cur_value = SELECTEDVALUE('Table1'[Column1])
VAR _count = CALCULATE(COUNTROWS('Table2'),'Table2'[Column1]=_cur_value)
VAR _result = IF(ISBLANK(_count),"yellow")
RETURN
_result
