2.112 Definition:
The distinguishing feature of a unit of homogeneous production is a unique activity which is identified by its inputs, a particular process of production and its outputs. The products which constitute the inputs and outputs are themselves distinguished not only by their physical characteristics and the extent to which they are processed but also by the technique of production used: they can be identified by reference to a classification of products (see paragraph 2.118.).
2.113 If a goods and services producing institutional unit carries out a principal activity and also one or more secondary activities, it will be partitioned into the same number of units of homogeneous production. Ancillary activities are not separated from the principal or secondary activities. Just like the local KAU, the unit of homogeneous production may correspond to an institutional unit or a part thereof; on the other hand, it can never belong to two different institutional units.
