Manage Applicability
You can use the Manage Applicability menu option to assign two types of applicability information to the components of a structure:
• Expressions — selections based on the option set defined for the product
See Options and Choices for information about options and choices.
• Service Effectivity — information such as date and serial number ranges to identify product configurations that remain serviceable
You can manage applicability of multiple items of an information structure or publication structure. In case of multiple selections, you can manage only the service effectivity information.
Selected Items
This field lists the items in the structure to which the applicability settings will be assigned. This field is enabled when you select multiple items (of the same type) in a structure and choose the Manage Applicability option.
* 
You can assign service effectivity settings to multiple items. It is not possible to assign applicability based on options and choices to multiple items.
The Manage Applicability window displays the flag Multiple Items Selected when you have selected more than one item in the structure.
Expressions
In this field you can use expressions to specify the option choices that apply to a component:
• Assigned Item Expressions — for the global use of an object
• Assigned Usage Expressions — for the object in a specific context
You can specify the choices by either selecting them from the option set assigned to the product (basic expression) or by using AND, OR, and NOT statements (advanced expression).
See Assigning Choices to Service Structure Objects, Assigning Applicability to a Parts List, Assigning Choices to Part Usages, and Assigning Applicability to Objects in a Folder for information on assigning choices to structure components.
See Defining Options with Advanced Expressions for information on using advanced expressions to define option choices.
Service Effectivity
In this field you can create , edit , and delete service effectivity objects and associate them to an object in a structure.
See Managing Service Effectivity for further information.
You can define service effectivity with the following information:
Field
Description
Type
The type of service effectivity information — the default choices are:
• Serial Number

When creating a service effectivity filter for a structure, this field details the context of an item/usage within its parent.
You must specify a context to activate the value entry fields.
Serial Number
The values for a Serial Number effectivity — the available fields are:
• Range — a finite range of values
Enter start and end values in the From and To fields.
• Single value — one single value
• Open start — all values up to a certain serial number
Enter the end number in the To field.
• Open end — all values from a certain serial number upwards
Enter the start number in the From field.
To specify a value of All, do not make any selections or add any values in this field. This option is available when you have specified a context in the Context field.
