Software Components
A software component bundles a set of packages that can only be delivered to customers together. All packages are distributed disjunctively among software components. This means that the objects in a package can only be delivered to customers with a software component. You assign objects to a software component by assigning the package (containing these objects) to a software component. In general there are several releases for each software component.
Support Packages can be imported into each software component separately.

The software component hierarchy
The software components delivered with SAP ERP form a hierarchy.You can use this hierarchy to work out which dependencies are implied by the use of a given software component. For example, SAP_HR uses objects from the component SAP_ABA, which in turn depends on SAP_BASIS.
