"Except" Operation in Flow

(0) ShareShare
ReportReport
Posted on by 22

Hi guys,

 

I'm just stuck and would appreciate your help.

 

I have two Sharepoint lists where I loop through and for each one I create an array (variable) with user IDs.

Let's say array A stores (all possible) 10 IDs and array B contains 7 IDs.

What I would like to get is a third array C where all IDs from array A are stored which are NOT in array B (in this case C would have 3 entries).

Is this possible without creating a for-each loop with another for-each loop inside.

 

I also tried one loop with the filter array action without any luck.

 

Thanks!

    The flow would run successfully as below:

    Hi @v-alzhan-msft , 

    Is there any other way to do an Except action? Doing a double Apply-to-each is non-intuitive. Also, I believe you'd have to perform another Apply-to-Each loop to determine which unique values are in the OTHER table.

    Just like we have Intersection and Union, we need Except. 

    Example:

    • Given two arrays, show which items exist in one and not the other

    This post has a nice example of Except: https://powerusers.microsoft.com/t5/Power-Automate-Ideas/Except-operation-in-WDL/idi-p/423351#M17791

    Have you made a test on it?
