Introduction to Rules, Node Types, and System Properties

This appendix lists which Model structure nodes and System Properties are valid when defining a Logic, Numeric, or Comparison Rule. For general information about System Properties, see System Properties.

Node Types and Valid System Properties when Defining Rules

When defining a rule, you specify which Model structure nodes participate in the rule. When defining a Logic Rule, Numeric Rule, or Comparison Rule, you can also specify whether a node’s System Property participates in the rule. You do this by clicking "Choose Properties" after selecting nodes from the Model structure. For example, you can contribute a value to a participating node’s runtime quantity by defining a Numeric Rule and selecting the node’s Quantity System Property. See Using Properties when Defining a Numeric Rule.

If you do not specify which System Property to use in a rule expression, Configurator Developer assigns an implicit node.property() reference, depending on the node type and the context established by the expression operator. For details, refer to the table Node Types and Implicit System Properties Used in Rule Expressions.

Node Types and Implicit System Properties Used in Rule Expressions

If the context is ...	and the node type is ...	Then the implicit System Property is ...
A logic expression in a rule (for example, Requires, Implies, Excludes, Negates, AND, OR, NOT, and so on)	BOM, Option Feature, Boolean Feature, or Option	State
	Any other type of node	None (invalid operand)
A numeric expression in a rule (for example, any arithmetic or comparison operator, including +, -, *, /, <, >, ADD...TO, SUBTRACT... FROM, and so on)	BOM or Counted Option	Quantity
	Integer or Decimal Feature, Total, or Resource	Value
	Any other type	None (invalid operand)

Configurator Developer also assigns an implicit Property reference if you do not specify a System Property when creating a runtime condition or text expression. Refer to the table below for details.

Node Types and Implicit System Properties Used in Runtime Conditions and Text Expressions

If the context is ...	and the node type is ...	Then the implicit System Property is ...
A display condition or text expression	BOM, Option Feature, Boolean Feature, Option	State
	Integer, Decimal, or Text Feature, Total, or Resource	Value

Note: For node types that have both the State and Quantity System Property, State takes precedence.

This section lists which nodes and System Properties can participate as:

• Logic Rule: First Operand and Second Operand

• Numeric Rule: First Operand

• Numeric Rule: Second Operand

• Comparison Rule: First Operand

• Comparison Rule: Second Operand

The table Rules, Valid Node Types, and System Properties summarizes all available node types and System Properties that you can use when defining Logic, Numeric, or Comparison Rules. When reviewing the table, consider the following:

• When using any_node.Selection(), the node must be mutually exclusive.

• When using any_node.State(), the node in First Operand is converted to a numeric value.

• Using any_node.State() in Second Operand causes an error when generating logic.

• A blank cell in the table indicates that the node or System Property is not valid, and is therefore not available when defining the rule.
