remove items from array that are also in 2nd array

(0) ShareShare

Posted on by kiki_musampa 27

Hi, 

 

I have 2 separate arrays in my flow that contain some of the same data. I want to remove the items from array (A) that are also present in array (B). 

So

(A) = [111, 222, 333, 444] 

(B) = [111, xxx, 444]

Should result in 

(C) = [222, 333]

 

Any clue what would be the best way to do this?

 

Thanks

    Hi , @kiki_musampa 

    According to your description, you want to remove items from array that are also in 2nd array.

    Here are the steps you can refer to , this is my flow:

    (1)The first three initial variable: 

    vyueyunmsft_1-1698975073812.png

    (2)The "Apply to each" step is like this:

    vyueyunmsft_2-1698975151158.png

    contains(intersection(variables('ListA'),variables('ListB')),item()) 
     
    Then the last compose is to test the ListC we get in the end , the result is as follows:
