Creating a dependency
A dependency (child object) is an entity that has a foreign key that references the base entity. The list of dependencies of the base entity allows you to select all objects that refer to the base entity.
You cannot create a dependency if the base entity does not have a primary key.
Go to [Menu] > [Configuration] > [Relations].
Click the button [Add…] in tabular form.

Click the button [Create] to add an entry or a button [Cancel] to exit the add mode without saving data.
When creating a dependency, a foreign key is created automatically.
