The -CR Lines tab is shared by all entity types. It contains the links between entities, called 'references'. In this tab, you can add references that are not already defined in the design of the entities.
You can add, delete a field in the table, or modify its value.
If the table is empty, click Add Field to display the root. Then click Add Field again to add a reference line in the table.
You can also click Add All Fields or Add Required Fields to display the root and references at the same time.
To add a value to a reference, click Add Value and then click on the new reference line in the value column. Click the button that appears to open a dialog box with the list of the entities available in your workspace in the current project.
