Custom Permission Level in Sharepoint 2010

SharePoint gives us the following Permissions Level by default.

	Full Control	Has Full Control
	Design	Can view, add, update, delete, approve, and customize
	Contribute	Can view, add, update, and delete list items and documents
	Read	Can view pages and list items and download documents
	Limited Access	Can view specific lists, document libraries, list items, folders, or documents when given permissions
	View Only	Can view pages, list items, and documents. Document types with server-side file handlers can be viewed in the browser but not downloaded

Suppose we have a requirement like we need to give the Permissions in such a way that a user can add and edit the item but will not be able to delete the Item in a list/Document Library or any other requirement which can not be fulfilled by using the default Permission Level.

In such scenario we can create a Custom Permission Level in which we can specify which permission set it should contain.

In this article we will see how to create a Custom Permission Level.

Step 1: Click on Site Permissions under Site Actions Menu.

Step 2: Click on Permission Level as shown in the below figure.

Step 3: Click on Add a Permission Level

Step 4: Select the appropriate ‘Permission Set’ by checking the checkboxes and click on Create Button.

Custom Permission Level has been created. 

Now use this Custom Permission Level as per your requirement.
