account_invoice_report_grouped_by_picking

Purpose

Allows printing customer invoices with their lines grouped by related stock picking information.

Features

account.move: Groups invoice lines by their related stock picking or the associated sale order when preparing data for the invoice report.
account.move: Includes section and note lines within the matching picking group so contextual notes stay aligned with the grouped content.
account.move: Adjusts grouped quantities for returns and refunds to avoid duplicating non-returned goods in the invoice output.
invoice_reporting: Displays grouped invoice sections in the report with picking references, sales order identifiers, and subtotals per picking.
invoice_reporting: Recomputes line subtotals per picking when only part of a line quantity is assigned to a picking and resets subtotals between groups.
