Delegations
Users with roles such as Approver, Purchase Order Creator, or Receiver (for example) can delegate, or assign, one or more of these roles to another user, for a specified period or indefinitely. See Delegating Roles.
For example, a user can delegate a role or roles to another user to allow the approval process to continue during temporary absences.
Roles Delegated to You
If there are any roles delegated to you, these will be visible on your dashboard. See User Delegation.
