Example of Validating Component Types Using Rules

You can define validation rules that automatically check whether the components associated with the structure are valid. You can specify the list of valid user item types for components in the rule.

Scenario

The following table summarizes an example of an item rule set and item rule that:

• Tests whether the structure associated with the item is of type Primary.

• Validates that only components of item types type1 and type2 can be added to a structure of type Primary.

Rule Set Field	Value
Business Entity	Item
Rule Set Name	Validate Component Types
Rule Set Type	Validation
Association Type	Item Class
Association Name	Root Item Class

Rule Field	Value
Name	Validate Component Types for Primary Structure
Description	Ensures that only components of item type TYPE1 or TYPE2 can be added to a Primary structure.
Valid Component Rules check box	Check box must be selected. Unlike other validation rules, rules that validate components don't have a Severity, because the item is being validated for only one aspect, and a degree of severity would be redundant.
IF Expression	[Structure].[Structure Attributes].[Structure Name] == "Primary"
Validation Condition	component_type("type1","type2")
User Message	Component type not supported for addition to this structure.
