Re: Who owns the data ?
Well, I can't speak for SAP, but I can speak about MS Dynamics (at the time still known as Navision.) Our vendor was trying to convince our company that data that was imported into Navision and later re-exported was subject to licensing fees for any and all future uses.
According to their interpretation of licensing rules pipe dreams, storing that data in a separate backend DB and accessing that DB from a web server would require a license for every user of the web portal.
That drove the last nail into the coffin of our use of overpriced CRM systems sold pimped out by such arrogant vendors.
