The way in which the product model's user dialog box (the form) functions depends on setup of the modeling variables, variable groups, validation rules, user profiles, and default values for the model. Together, these structures define the appearance and behavior of the user dialog box with its tabs, sections, and fields.

Until nodes are added to the modeling tree, the product model cannot be used to configure items. This is because the modeling tree, which determines the configuration process, is missing. However, you can test the user dialog box design by creating an order, item requirement, or quotation and then configuring it (as a test) in the , , , , , or sections. You will then be able to verify that the product model's user dialog box works as expected.

You can also test the form by clicking > in the form or by clicking in the form. In both cases, the product model's user dialog box will be displayed.
