Editing system tables

Kentico allows you to modify some of the system objects and add your own custom fields.

In previous versions, this type of customization was provided by the System tables interface. In Kentico 8 and newer, you can do the same by editing the corresponding classes in the Modules application.

The following table describes which Module and Class you need to edit to access the fields of the original system tables:

Original System table	Kentico 8+ Class
Contact management - Account	Modules -> Contact management -> Classes -> Contact management - Account
Contact management - Contact	Modules -> Contact management -> Classes -> Contact management - Contact
Ecommerce - Customer	Modules -> E-commerce -> Classes -> Customer
Ecommerce - Option category	Modules -> E-commerce -> Classes -> Option category
Ecommerce - Order	Modules -> E-commerce -> Classes -> Order
Ecommerce - Order item	Modules -> E-commerce -> Classes -> Order item
Ecommerce - Shopping cart	Modules -> E-commerce -> Classes -> Shopping cart
Ecommerce - Shopping cart item	Modules -> E-commerce -> Classes -> Shopping cart item
Ecommerce - SKU	Modules -> E-commerce -> Classes -> SKU
Group	Modules -> Community -> Classes -> Group
Media file	Modules -> Media libraries -> Classes -> Media file
Newsletter - Subscriber	Modules -> Email marketing -> Classes -> Newsletter - Subscriber
User	Modules -> Membership -> Classes -> User
User - Settings	Modules -> Membership -> Classes -> User - Settings

When creating new fields for a system class, the Required flag is always false and cannot be edited. This is necessary to ensure that the default system procedures continue to work correctly. However, you can enable the Required flag for fields in alternative forms.

For more information about creating new fields for system classes, see the example in Customizing product option forms.
