Delivery Date Exclude Service

This module gives you control over how service products influence the expected delivery date of a sales order.

On the product form, in the Sales tab under the Extra Info section, a new checkbox called "Affect Delivery Date" appears. It is only shown for products of type service, so it stays hidden for physical goods.

• By default the checkbox is unchecked. When a sales order line uses a service product with this box unchecked, that line's lead time is completely ignored when Odoo works out the order's expected delivery date.
• If you tick the box on the service product, its lead time is counted again, just like a normal product.
• Physical goods always keep contributing their lead time, as before.

The module also makes the sales order date selection more robust: when Odoo gathers candidate expected dates, empty values are filtered out before choosing the final one, so a missing date on one line does not break the calculation.

It touches the product template, sales order and sales order line models, and adds the checkbox to the standard product form view. No new menus, reports or scheduled jobs are added.
