Supply component, release item

The supply components (SCs) are also known as release items (RIs). A release item is the smallest unit (file) supplied as a component of a product – for example a load module, syntax file, or the like. The file name includes the name and version of the release unit.

A product (release unit) can refer to its release items without using their names. The mechanism involved here employs an internal ID assigned to each release item and known as the logical ID.

Once it is installed, a release item is known as an installation item. The installation items are registered in the SCI.
