How can you remove audit flag rules for Expense Reports

Summary:

My organization processes individual expense reports and Corp-cards through expense reports in Oracle. Because of this some individuals have large expense reports that need to be approved and audited. Our organization does not have any individual or monthly tolerance limit for expenses but our expense reports are constantly adding these flags. We audit all our expense reports, but because of these flags it an extra step to remove the flags before submitting them for payment.

Where can I see the rules for these flags and remove them?

Thank you in advance!
