Hi,
If you go to the https://support.sap.com/release-upgrade-maintenance/pam.html site you should be able to find what you need. The PAM or Product Availability Matrix has really grown and is actually pretty good for the newer stuff. If want to know about the older certification stuff you should go to the SAP ASE wiki page: https://wiki.scn.sap.com/wiki/display/SYBASE/ASE+Certification+Reports
Thanks,
Dawn Kim
