SAP’s maintenance strategy, as well as the support offerings, have two dimensions: time and scope. In terms of the timeline, SAP defines three maintenance phases: mainstream maintenance, extended maintenance, and customer-specific maintenance. In terms of the scope, SAP offers three levels of support offerings: SAP Standard Support, SAP Premium Support, and SAP MaxAttention.

The 7-2 maintenance strategy was introduced in 2008. It applies to new releases of core applications of SAP Business Suite as of November 2008, as well as add-ons and enhancement packages. This includes SAP NetWeaver 7.0 and add-ons. For more information refer to SAP Service Marketplace (http://service.sap.com/maintenance).
