Expense Audit List

Summary

How to select Audit for Employee for all expense reports

Content

Hello:

We are implementing the Expense module for credit cards, and was told at some point, an employee could be chosen to have all their expense reports audited until they were taken off the audit.  These would be repeat violators for one thing or another.  I thought maybe the audit list reason of "violates undefined rule" would do it, but it doesn't.  A couple of questions if anyone knows:

1)   What is the violates undefined rule for and how is it used?

2)  How can you have all expenses audited for an individual?
