There is no such kind of feature available in standard Odoo.

@ Cybrosys    I think this is a misunderstanding.

It is not about an additional note at the end of the delivery note, but about the notes and sections that Odoo offers together with the selection of products when creating quotations. These are displayed on the quotations, orders and invoices, but not on the delivery notes. We have not yet found a way to view and print this information on the delivery notes.

However, this would be important for individual deliveries because it would additionally group the goods on delivery and thus make it easier to check deliveries for completeness. 

Hi,

Please try this code:

< template id="report_delivery_document_inherit_custom_module" inherit_id="stock.report_delivery_document">
< xpath expr="//div[@name='signature']" position="after">
            < p t-field="o.note"/>
        < /xpath>
    < /template>

Hope it helps
