Full Control for a MS List without being Site Owner

[chriscanning]

Hi,

I have an issue where we have SharePoint list items that have been allocated individual permission via Power Automate. I want to have 'full control' allocated to each item similar to how SharePoint Site Owners still retain full control of the overall list and the individual permissioned items within it. 

I can't add the user group into the the site owner group as I don't want members of this group to have full control / access of the entire site, only the specified MS list.

I tried giving the group 'full control' in the MS list outside of the owner group, but it doesn't seem to translate into permissions for the individual items.   

Is there a way around this?

Try these two things:

1. Grant full control permissions at the "list" level - this will give full control for list items inheriting permissions from the list: I think you already this as per your screenshot.
2. After step #1, grant full control permissions on each individual item via Power automate flow - this will give full control for list items with unique permissions.

@ganeshsanap ,

Thanks for the reply. Yes I have continued looking into this and came to the same conclusion. Any idea how to do this for a security group as opposed to the SharePoint site members group?

You can first use EnsureUser endpoint and then roleassignments/addroleassignment endpoint to assign the permissions to security groups on the individual list items.

Refer this article for related information: SharePoint Online: Grant Permissions to Azure AD Security group using Power Automate and REST API - here I am granting permissions at "site" level but you have to grant permissions at "item" level (similar endpoint as you are using for granting permissions to users/members).
