ITA - Fattura elettronica - Export ZIP

This module adds a bulk export tool for Italian electronic invoices. From the list or form of electronic invoice XML attachments (both outgoing fatturapa.attachment.out and incoming fatturapa.attachment.in), an action named "Download ZIP e-invoice XML" opens a small wizard where you confirm the file name and press "Export zip".

• The wizard packs the selected XML files into one ZIP file, which is stored as an attachment and opened for download.
• Each exported XML record is linked to the ZIP it was included in, through a read-only "Exported ZIP" field shown on the list and form views.
• Search filters "ZIP Not Exported" and "ZIP Exported" let you quickly find files that still need to be exported or that were already handled.
• Safety checks: if a selected file was already exported, the wizard stops and asks you to remove the previous ZIP first; if a file has no XML content or no name, it also stops with an error.
• The default ZIP name is built from a translated label plus the current date and time.

It touches the electronic invoice attachment models and the related list, form and search screens, and is available to users with invoicing access rights.
