Example 4.1. Define an Eliminate Sources Based on Rule Evaluation.

The computer factory has three values for the COLOR attribute:

• BLUE
• BLACK
• BEIGE

Comparison is case sensitive:

• Build a maximum of 3 BLACK computers consecutively.
• Space BEIGE computers so at least a minimum of two other colors are built between each BEIGE computer.

Note: The Spacing rule does not say that there should be 1 beige computer out of every three. Results from other rules (and what items are in the range) may place 5 computers with other colors after a beige computer. This is perfectly acceptable.

Rule Type	Attribute Name	Attribute Value	Rule
G	COLOR	BLACK	3
S	COLOR	BEIGE	2

Configuring this rule is done in three segments.

Example 4.1.1	Create an Eliminate Sources Based on Rule function block.
Example 4.1.2	Enter values for the rule definition arrays.
Example 4.1.3	Add a Record Attribute Rule function block.
