In your domain model, right-click entity Package and select ‘Generate overview pages’. In the popup also select ‘Booking’. This will generate a page ~_Overview and ~_NewEdit for each of them, and and menu.

On your page Package_Overview, add a dataview with as ‘Datasource‘: ‘Listen to datagrid’.

In that dataview add a datagrid with datasource ‘over association’. Set it to Booking_Package->Booking.

To the buttons ‘New’ and ‘Edit’ add you page Booking_NewEdit
