title: Item level permission for sharepoint custom list
body: <p>I have created a custom list with work flow associated with that. The workflow takes the item through different levels of approval.</p>
  
  <p>My workflow scenario is like say an initiator add an item, which will go to manager for approval. When the manager approves, few columns in the current list will get updated. On manager approval it will be forwarded to head of department. Again when the Dept head takes an action, the column values of the list get updated. For all these users i have set Contribute permission. But the problem is that an item started by an initiator should not be editable or deleted by other users using the pull down menu that appears for each item. Only the owner of the item and manager should have permission to edit it using the pull down menu. When I tried changing the edit access for the item through Advance settings-->Item level permission --Edit access being set to "Only their own" while manager or dept head approving I get an access denied error message.</p>
  
  <p>Can any one please suggest me what is the work around for this?</p>
