The only people are I've met that all love SAP are SAP employees living in my area, which isn't too surprising I guess.
SAP is such a pain. Our org got married to it years ago and there aren't budgets big enough to undo it. At least it's stable enough.
Oracle is another ballgame -- they're just terrible.
Pointedly: If there were organizations that reproduced their modules independently, and integrated into them well enough to "stay on one system" at the finance level until they're able to slowly pick away at replacing each one and data collections into a main db in a sane, nonconvoluted or expensive way? (Unlike SAP)
