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