Hi Hakan,
I'm quite certain I don't have any contracts in place. I have heard NOTHING about needing a contract, or that it was an option, or a requirement?
I know that none of my existing companies have any contracts with SAP, though they bought advantage before or right around the time Sybase bought out extended systems.. I know a couple of licenses were bought after Sybase took over, but we have never had any contracts in place with SAP. In the olden days we were considered ADS Partners.
Does that help?
