Assigning Expressions to Parts
You can assign expressions to parts or configurable modules. Consider this information for assigning expressions:
An option set must be assigned to the part or its context, or to the root part or its context. The context is a product or library to which this part belongs.
If the option set was created with Allow Assignment of Expressions to Non-Configurable Items set to No, you can assign expressions only to configurable modules. If the option set was created with Allow Assignment of Expressions to Non-Configurable Items set to Yes, then you can assign expressions to both standard parts and configurable modules.
You can assign advanced expressions, if advanced expressions are supported for your site and product.
To assign expressions to a part:
1. Go to the part information page and click Assign Expression from the Actions menu.
2. The Assign Basic Expression window opens, listing the options and choices from the assigned option set. For steps for defining basic expressions, go to Defining Basic Expressions.
* 
If the toggle action is available, you can toggle the window between the basic expressions and the advanced expressions. The icon appears if the current assignment type disagrees with the setting of the Supported Expressions preference setting, or if the preference is set to both types.
3. When finished expressions, click OK. The expressions you assigned are listed in the Assigned Item Expressions column in the tree view and the Uses table.
* 
You can configure the tables to add the Assigned Item Expressions column.
