To delegate work items for yourself

1. In the User Console, select Home, Out of Office Assistant.
   The Out of Office Assistant screen appears.
2. Click Add User.
   A select user screen appears.
3. Search for and select one or more users to act as delegate.
   The users are added to the delegate list.

Environment

Identity Manager

Cause

The Admin Role giving users access to the Out of Office Assistant task, e.g. Self Delegator, did not have a proper Member scope rule. 

Resolution

On the Members tab of the Self Delegator admin role, ensure the scoping is set correctly. 

If, for example, you want all users to be able to select any other user as a delegate, the Member Rule would be that all users are members of the role, and they manage all User objects.
This can be modified as desired so users can search only for users in their own department, etc.
