Expense Report Correction Restrictions
Depending on permissions set by your system administrator for your Expense Class or Functional Role, you may not be allowed to correct the net reimbursement amount of the expense report.
When this is the case, you are not allowed to change the Expense Incurred amount, or any field that would affect it, which by extension, would also change original net reimbursement amount. Therefore, throughout the various wizards, fields that can affect the Expense Incurred amount are disabled and the link for adding expenses is also disabled. See a complete list of disabled fields.
If you are allowed to change the reimbursement amount but have already been paid for the original amount, you will be issued a voucher for the difference between the original and corrected amounts.
