The first block, when you create a Routing Logic Module (RLM) must define the source range in which the item will be evaluated.

Example

A computer factory creates a Routing Logic Module to select purchase orders for computers that will be classed as CLASS1 computers.

Where and/or what orders to be evaluated needs to be defined.

The following options define a basic range source.

Option 1.1	Use a range as a source.
Option 1.2	Use a spread range as a source.
Option 1.3	Use a Query as a range source.

Criteria sets include the range in the definition, you can also use it as the first block in the RLM.

Option 1.4

Use a criteria set as a range source.
