When creating a new expense report, the system will provide you with a blank form. If you are a frequent traveler, you may wish to update your user defaults to help save yourself some time. By editing your user defaults, you tell the system what to auto-populate in some of the repeated fields.
For example, if you are frequently traveling in-state for meetings, you can tell the system to create an expense report that specifies "In-State Travel" for the Business Purpose.
