SAP Add-On Installation Tool

SAP offers a wide range of add-ons that you can use to enhance your standard SAP system. These add-ons can be Industry Solutions, plug-ins, or customer-specific development projects.

SAP Add-On Installation Tool (transaction SAINT) was developed to enable users to install and upgrade add-ons directly from their standard SAP system. If necessary, you can also use this tool to uninstall ABAP Add-Ons. However, this function is only available for Add-Ons that are explicitly intended for deletion, and that are marked as deletable. You do not need to access the operating system or restart the system.

SAP offers Preconfigured Systems (PCS or SAP Best Practices) that can also be installed using SAP Add-On Installation Tool. A PCS reduces the amount of work needed to install and customize an industry-specific solution. For more information about preconfiguration with SAP Best Practices, see Installing Preconfigured Systems (PCS) in the SAP Add-On Installation Tool documentation.

The SAP Add-On Installation Tool is delivered in its own Support Package, the SPAM/SAINT Update. We enhance and improve the tool constantly, and recommend that you always import the latest version from SAP Support Portal before performing an installation or upgrade.

Since 2009, you require maintenance certificates to import SAP Support Packges with the Support Package Manager. You can use SAP Solution Manager to request these maintenance certificates and to automatically distribute them to the managed systems. The importing of Support Packages for software from third-party vendors is not affected. You can import this type of Support Packages without maintenance certificates. For more information, see the SAP Support Portal under http://service.sap.com/maintenancecertificate and SAP Note 1240265 .

• Add-On Installation Tool checks compliance with import conditions, such as the SAP NetWeaver Release and the Support Package level of the various software components, accepting or rejecting them accordingly.

• To simplify the import process, the complete installation or upgrade is first put together in the customer system from the add-on package, any Support Packages that are needed, and any Conflict Resolution Transports (CRTs).

• Installing and Upgrading Add-Ons

  • Restart capability

    The installation itself can be restarted, like the Support Package import process.

  • Special import procedure

    You can use a special import procedure to reduce downtime while importing add-on packages (see Import Mode: Downtime-minimized in the SAP Add-One Installation Tool documentation.

  • Start time definition

    The separate phases in SAP Add-On Installation Tool are grouped into modules. You are free to choose any start time you want for these modules.

  • Background Processing

    You can also schedule the modules with defined start times for background processing.

• During the uninstallation of ABAP Add-Ons, the system determines all content of the Add-Ons to be deleted and all dependencies to other content, and checks how to proceed with the objects. The SAP Add-On Installation Tool makes sure that the system is in a correct status after the uninstallation.

  Note

  Not all ABAP Add-Ons can be deleted. You an only perform the uninstallation if the Add-On fulfills certain prerequisites and was designated as deletable when it was created.
