We have SharePoint group: HR.
We have a list with one of the columns as Assigned To and this list is displayed to users via a list view web part by filtering Assigned To=[Me]. The list has unique permissions set to HR group.
Issue is that, although the list view web part shows the items assigned to individual logged in users ([Me]), users belonging to HR group can view all the list items via the default list view URL. That's fine!
Is there anyway to prevent users from editing the items Assigned To other users (they could change the assigned to value or other values via the edit form)?
