Logical Units

A Logical Unit is a business object such as a "Customer" or "Sales Part" object that defines the attributes, methods and relationships to other logical units. A typical Logical Unit consists of an Oracle table in the Data Storage Layer, PL/SQL Procedures and Functions and an Oracle View in the Business Logic Layer, and one or more Application Forms in the Presentation Layer.

These administration windows can be used to list existing logical units in the installation and do operations such as activating Logical Unit Rowkey.
