Prevent users from entering a value inside a SharePoint field if they are not inside a SharePoint group

[johnjohn123]

We are working on asset management system inside SharePoint online, here is the scenario:-

1. We have 2 SharePoint groups; Admins & Regular users
2. Inside the Assets list we have a field named "Owner" of type people/group
3. Now if the login user is not admin (is Regular user), then the Owner field should be disabled and auto populated with the login username.
4. while if the login user is an Admin then the Owner field should be enabled and allow the admin to enter any owner.

Now i am not sure how i need to implement this to prevent regular users from entering values inside the Owner field other than their username ?So if we customize the SharePoint list form using Power Apps, will we be able to implement the above scenario ? of enabling/disabling the Owner field based on the user's permission inside SharePoint?

Hey @johnjohn123 ,

There are numerous informative blogs and videos on this subject. Use the URL below that Reza provided as an example.

Additionally, you can use Power Automate to call the REST service in SharePoint to determine whether a user is a member of a group and receive a Boolean value that you can use in PowerApps to enable or disable the column.
