I have list having item level permission "Read items that were created by the user " and "Create items and edit items that were created by the user"
I am able to open the item from tasklist but not able to open the from the list item itself.
When I try open the request from the approver window i get an the following error , but when i give item level permission to "Read all items " it works fine. In our case I need "Read items that were created by the user" privileges. If I assign the Manage list permission to the approval user than it works, but I don't want to give approver these rights.
