Matching attributes are reference attributes of two related business objects that describe the same relation. Consider an example where Customer object has attribute Accounts that keeps track of all accounts of the customer, and Account object has attribute Holder that refers to the customer holding this account. These two attributes are declared as matching. The user creates a new account and selects a customer as its holder. When looking at the customer details the user will see the newly created account in the customer’s account list.

Since objects in Configuration Tool are edited separately, the configurator needs to specifically nominate attributes of related objects as matching to establish a two-way connection. Otherwise they will be treated as two separate one-way connections between the related objects.
