You may assign a delegate in the travel and expense system, another user who is authorized to complete work on your behalf. However, first be sure to confirm with your department that this is allowed.
In the system you can assign a delegate permission to:
Assign a preparer delegate permission to prepare expense reports on your behalf. Click the checkboxes to assign their permissions (Figure 3).
Assign an approval delegate permission to preview or approve expense reports pending your approval on your behalf. You and the delegate must both be approvers. Note that assigning an approval delegate permission to approve reports on your behalf can only occur while you are on a leave of absence. Click the checkboxes to assign their permissions (Figure 4).
