To manage permissions, the user must have the Manage Permissions permission. You must be a member of the Hierarchy Managers group to edit permissions.
To create unique permissions for an app, follow these steps:- Browse to the app, click the Library or List tab of the Ribbon, and click the Library or List Settings button in the Settings group.
- Click the Permissions for This Document Library link in the Permissions and Management section. The Permissions page appears.
- Manage the permissions as you would for a subsite by breaking inheritance and managing the permissions uniquely for the list. Managing permissions on apps is the same as managing permissions for subsites.
For example, you can share a site by clicking the Share button in the upper right corner of the screen. Alternatively, you can share a document by using the Share button located in the ellipsis next to that document as outlined in the next procedure.
With SharePoint Online, you can even share a document without requiring the other person to log into your SharePoint site.
Follow these steps to give permissions for a document, item, or folder in an app library:- Browse to the app where the item, document, or folder is located.
- Click the ellipsis next to the item and click Share. The Share dialog box appears.
- Enter the name, email address, or group, and then select the permission you wish to give — Can Edit or Can View.
- Click the Share button to give permissions.
For an item in a list app, the process is a bit different. For individual list items, you manage permissions separately in much the same way you would for a subsite. To access the permissions for the individual list item you want to manage, click the ellipsis next to the item and choose Manage Permissions from the Advanced drop-down. However, you cannot share out list items individually like you can actual documents because the list item is part of SharePoint, whereas the document is a file unto itself.
