Import Support Package Stacks

SAP ships quality enhancements, program corrections, and updates for SAP NetWeaver in Support Packages. Support Packages are grouped in Support Package Stacks (SP Stacks), which can include both ABAP and Java Support Packages and Kernel Patches. When released, an SP Stack contains the optimum combination of Support Package and Patch levels for all NetWeaver components. The Support Packages and Patches listed in an SP Stack must be implemented together.

Support Package Stacks are available on SAP Service Marketplace at http://service.sap.com/sp-stacks. Information about the availability of Support Package Stacks is also available here.

The Support Package Stack Guide gives you detailed information about importing Support Package Stacks. It is updated for each new SP Stack. You can find the guide on SAP Service Marketplace at http://service.sap.com/instguides.

Install and update Add-Ons

SAP ships individual SAP NetWeaver components as Add-Ons. These Add-Ons are updated at more frequent intervals than SAP NetWeaver. Between SAP NetWeaver Releases, you can use the SAP Add-On Installation Tool to import the latest versions of these Add-Ons. SAP also ships other functions, such as industry solutions, as Add-Ons. You can also use the Add-On Installation Tool to import these additional functions, if required.

Add-On Installation Packages and Add-On Upgrade Packages are available on SAP Service Marketplace at http://service.sap.com/installations.
