These two reports are found in the cooresponding tab (Time or Expense) within My Reports as Time Sheet Reports and Expense Report Reports. Both reports require the user settings for Time/Expense Report Viewer and/or Invoice Manager as referenced in the User Profile section. Users without one or both of these settings will not have access to the reports.
These reports differ from time and expense reports because reporting is at the time sheet and expense report level. One line is reported per time sheet or expense report, as opposed to time and expense reporting with line item entry detail for all entries.
In addition to viewing these reports, an Invoice Manager can edit specific time and expense entries within time sheets and expense reports which have already been approved. The Invoice Manager is not required to have been the approver of the time sheet or expense report in order to perform these edits to the item entries.
