In LibreOffice you can register different data sources. The contents of the data fields are then available to you for use in various fields and controls. Your system address book is such a data source.
LibreOffice templates and wizards use fields for the contents of the address book. When activated, the general fields in the templates are automatically replaced with the fields from the data source of your address book.
In order for the replacement to take place, you must tell LibreOffice which address book you use. The wizard asking for this information appears automatically the first time you activate, for example, a business letter template. You can also call the wizard by following the steps listed below.
The address book data is read-only in LibreOffice Base. It is not possible to add, edit, or delete address data from within Base.
To call the Address Data Source wizard, choose File - Wizards - Address Data Source .
Now your data source is registered in LibreOffice as the address book. If you now open a template from the Business Correspondence category, LibreOffice can automatically insert the correct fields for a form letter.
