What Are Computed Expressions?
Integrity Lifecycle Manager can perform simple or complex calculations of item data in fields, charts, and reports using computed expressions. A computed expression is any combination of mathematical or logical operators, constants, functions, and Integrity Lifecycle Manager fields that evaluates to a single value. This functionality offers more power and flexibility to your Integrity Lifecycle Manager database by dynamically producing specific information about your item data.
