How to Delete a Property from a Profile Definition
You can delete properties and property groups if you do not need them in a profile definition. For example, you add seven properties to a profile definition, and you may find that you need only six of the properties on the Web site. When you delete a property group, all properties in that group are also deleted. You cannot recover a profile definition after you delete the profile definition.
To delete a property from a profile definition
Expand Commerce Server Manager, expand Global Resources, expand Profiles, expand Profile Catalog, expand Profile Definitions, and then click the profile definition from which you want to delete a property.
In the Properties list, select the property or property group you want to delete, and then click Remove.
In the Delete confirmation dialog box, click OK.
To save the profile definition, click the Save icon on the toolbar.
The changed profile definition is saved. It no longer contains the property or property group that you deleted.
