ITA - Documento di trasporto - Prelievo raggruppato

This module connects batch pickings (groups of transfers handled together) with Italian transport documents (DDT).

On a batch picking form you get a new "Create DNs" button. When clicked, the system looks at the transfers in the batch that do not yet have a transport document, groups them by sender and recipient, and creates one document per group. Each new document is linked to the batch and to the relevant transfers, and the type of document is chosen automatically based on the operation type of the batch.

After creation, Odoo opens the resulting documents: a single document opens directly in form view, several documents open in a filtered list, and if nothing was created the window simply closes. The button is hidden when the batch is already done or when all its transfers already have a document.

A smart button on the batch shows how many transport documents are linked to it and opens them. A technical indicator records whether every transfer in the batch already has a document, which drives the visibility of the creation button.

On the transfer list view, the transport document is available as an optional (hidden by default) column, so you can see which document each transfer belongs to. The module is installed automatically when its dependencies are present.
