Expression
The Expression processor allows you to write an expression which may encompass the logic of a number of other EDQ processors and other functions, using an abbreviated expression language.
Expressions are useful where the required logic of a processor can be expressed most logically and succinctly by writing an expression, rather than by configuring several processors. This is commonly the case when performing mathematical operations, for example.
Inputs
The Expression processor may take any number of inputs, of any type, with the exception of formal Date attributes.
