It's a racket. It might not be as common today, but I remember when there were lots of people whose career was based on their SAP expertise, and the reason they got hired was that no one else could deal with that crap if anything went wrong. Once a lot of those people get into big companies, their career is based on preventing their employer from dumping SAP (or equivalent) for something better. So, it's like they have agents inside all the large companies that use their stuff.
