## 8.3.1 General

The OPC UA Variable Type MaterialLotType describes a lot of materials, i.e. the type of material and its quantity expressed in base unit of measure and, optionally, in logistics unit of measure.

Remark. Both units of measure are carried out to correctly manage partial logistic units.
