icon in the Structure tab toolbar. The Edit Filter window is displayed.3. Select the Attribute Filter tab.
 | If no expressions have been defined the Attribute Query Expression window is immediately displayed for defining new query expressions. If attribute queries have been previously defined they are shown in the expression table in the Attribute Filter tab and you must click the Add button to create a new attribute query expression. |
4. Use the drop-down menu in the Type field to select a item type (parts list, part or parts list item) to include in the attribute query expression. Attribute filtering expressions apply to the selected item type and its sub types.
| | Attribute filtering expressions written for a selected item type will only return items of that type and sub types even if the same attribute name applies to other item types in the parts list Item types for which no attribute filtering expressions have been written will always be displayed in the parts list. |
 | You can use the Service Parts preference Excluded Part and Dynamic Document Subtypes to restrict the list of item types provided in the Type field. For more information, see Setting Service Preferences |
5. Use the drop-down menu in the Criteria field to select the attribute to filter by. The available attributes are dependent upon the item type selected in the Type field. The attribute list includes standard Windchill attributes and those created by your system administrator.
| | You can make more than one choice from the Criteria menu prior to completing the attribute query expression. All choices appear as individual comparisons in separate rows. Expressions can be deleted by clicking on the Remove Expression  icon.For more information about using multiple comparisons in a single attribute query expression, see Using Multiple Attribute Filter Expressions. |
6. Select an operator from the drop-down menu to the right of the attribute. The list of operators depends on the attribute selected for the comparison and can include one or more of the following:
Operator | Definition |
|---|---|
= | Equal to |
≠ | Not equal to |
› | Greater than |
≥ | Greater than or equal to |
‹ | Less than |
≤ | Less than or equal to |
Not Set | The attribute value is not set, its value is blank. |
7. Enter an attribute value to the right of the operator.
| | Text values are case insensitive. Use wildcards for text entries (* for a multiple character match and ? for matching a single character) in the value field to include a larger number of matching items. |
| | Some attributes require the selection of a choice from a drop-down menu. Other attributes provide the ability to search for a value by clicking a find  icon. |
