Paraphrased/Taken from the press release:

SAP AG and Novell announced that they have extended their relationship to offer a new joint support solution for customers who run their SAP applications on SUSE Linux Enterprise Server (SLES) from Novell. With today’s announcement, customers who run their SAP applications on SLES now have a single support entry point, from the operating system through the application, to streamline resolution of support incidents, reduce complexity and lower the total cost of ownership. Branded as “SUSE Linux Enterprise Server Priority Support for SAP applications,” the offering is available starting today and is a maintenance and support package provided by Novell that will be integrated through the SAP Solution Manager application management solution into the SAP global support backbone for managing the entire life cycle of SAP applications. Through this agreement, SAP continues its commitment to deliver value to customers who choose to run open source and commercial software based on open standards. The announcement was made at SAPPHIRE ’07 Vienna, SAP’s international customer conference being held in Vienna, Austria, May 14-16.

Novell and SAP plan to work together in the future to further optimize SLES for SAP application platforms, including SAP NetWeaver and SAP Business Suite. Further, SAP recommends SUSE Linux Enterprise Server as a preferred platform for customers who want to deploy SAP applications on Linux. The combination of SAP Business Suite on SLES will provide consistent manageability of SAP applications in mixed, open source and commercial software environments.
