Good morning,

I am seeking guidance on building a flow that modifies one of my lists in SharePoint. Essentially, I have a list of items which need to be reviewed by individuals that is being tracked in another list. I've been able to develop a flow that automatically assigns a set number of items (through manual input) to each reviewer in the list. The troublesome part for me now is I now need to assign only 50% of the items, based on the creator of the item (specialist) as well as another variable, the 'code'. Below is my flow currently which is functional but I am not sure how to assign only 50% of the items, based on the person as well as the code. I've tried to use variables to store the count of items, the person and the code but the assignment part is eluding me.

Any help is appreciated.

You are right, sorry for the two mistakes!

['value'] was missing, and I should have used take() instead of first()

Try with the following instead

take(body('Get_items_from_COMs_for_Review_-_Findings_Tracker')?['value'],div(length(body('Get_items_from_COMs_for_Review_-_Findings_Tracker')?['value']),2))

In ths following image I am using a "Get items" action block with its default name

Hope this helps

Re: Difficulty with modifying list based on multiple Variables

Hello @efialttes ,

I really appreciate the response. I attempted to apply your solution and it seems to be differnet when using get items. For example, I receive this error when directly applying your solution:

first(body('Get_items_from_COMs_for_Review_-_Findings_Tracker'),div(length(body('Get_items_from_COMs_for_Review_-_Findings_Tracker')),2))
When Applying logic directlyAttempt at modifying expression to take in an array.
first(body('Get_items_from_COMs_for_Review_-_Findings_Tracker')?['value'],div(length(body('Get_items_from_COMs_for_Review_-_Findings_Tracker')?['value']),2))

I suspect the second one has something to do with the fact that the values dynamic content has an extra paren? zi am not sure. I've attempted to rearrange the parens in different ways but it keeps providing this error.

What I understand is that the list of items is stored in this array, right?

...and you need to work with a 50% of its items, right?

A very simple approach is to calculate array's length (N), divide it by 2 (N/2), and get the first (N/2) items from this array as the input for your Apply_to_each loop.

This can be done by means of variables and expressions. So you can use a "Initialize variable" action block, assign it a name, select as type "array", and use the following expression as value:

Please note in my example I am using as an input array the result of a "Get items (properties only)" action block; I guess in your project your are using a "Get items".

Hope this helps
