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, or customer-specific development projects.
SAP Add-On Installation Tool was developed to enable users to install and upgrade add-ons directly from their standard SAP system.
The installation itself can be restarted, like the Support Package import process.
You can use a special import procedure to reduce downtime while importing add-on packages.
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.
You can also schedule the modules with defined start times for background processing.
