Update people picker field (multi person) from another list randomly
I have 2 list.
List 1 has all the items created by the user
List 2 has list of unique email address
My Requirement is to populate 3 email address from List 2 into the List 1 people finder field for each item. So basically all the emails in List 2 should be evenly distributed among all items in List 1 in pair of 3. I know it may depend on the number of emails in List 2. So even if we could closely assign equal number of items to each emails that should be ok.
Since there is not relation between List 1 & List 2 i am not sure how this can be done in Power Automate
So, that being the case, get all the items from list 2, distill it down to a plain array of email addresses using a Select action where what you're selecting is simply item()?['Title'] (press the little button to break out of key-value mode) assuming all the email addresses are in the Title column of a SP list.
Now you can set an Until loop with a timeout of 3 iterations to build up a JSON object that represents the multi-person column then update the item with that.
