Supply group, release unit

The supply groups (SGs) are also known as release units (RUs). A particular release unit may be a component of more than one supply unit.

A release unit consists of one or more technical units, for example programs, DSSM subsystems, prelinked modules, etc.

A release unit may be supplied more than once; an initial delivery may be followed by correction deliveries. The process of installation turns a release unit into an installation unit, which is registered in the SCI.

The designation and attributes of a release unit correspond to those of an installation unit (see "Installation unit (IU)").
