"SAP expects users to rid their ERP software of any customization"
Oh sure. Forget the millions and months (years ?) you put into your current three-legged horse and move to virgin land where you can start all over again (and pay all over again).
I understand that this is a brilliant plan for SAP. It's a shitty plan for its customers and they're not buying it.
That's because SAP has mistaken itself for something that holds its customers by the balls, and makes no bones about squeezing. Well, SAP's customers have other things to do then give their revenue to SAP.
Funny that, ain't it ? Would seem to me that you didn't need an MBA to understand.
You do need a shred of decency, though.
