You should be aware that any kind of expense software used by a university would have to scale up to thousands of users and would, of course, need to be totally and utterly obfuscated. If any old category theorist or quantum physicist can figure it out it would result in pandemonium!
Peoplesoft... Now there's a real university expense reporting platform. Whatever you do, don't go into expense reports under the main menu. That will corrupt your account and cause you to cease being paid. Change your role from student, employee, or faculty to petitioning_supplicant34, go into the cost reporting section, flip the null flag, then go into history and enter your expenses under category T311802, unless it's Tuesday or a prime numbered day of the Julian calendar. If that doesn't work and it's not a Tuesday or prime Julian date, request an update from Pam in accounts, who will be on vacation until the next solstice.
You should try the Defense Travel System. After submitting my itinerary once, probably the 5th time I'd taken the exact same quarterly trip, using the exact same system, my ticketing never came through. I finally realized it and called one of the travel people. He said "Once you hit submit, you have to go back and check on this other page, in about an hour, to make sure it actually went through, otherwise you have to resubmit."
Wat? This is in production? On a financial system?
