Stock Picking Sale Order Link

This module makes it easier to move between inventory and sales information. On the Stock Transfer (picking) form, a new smart button labelled "Sales Order" appears in the button box at the top of the screen, next to the other status buttons.

• The button is only shown when the transfer is actually linked to a sales order; transfers with no sales order do not display it.
• It is visible to users who have the standard inventory user access right.
• Clicking the button opens the related sales order form directly, so users do not have to search for the order manually.

The module works by extending the existing stock.picking model with a new action and by adding the button to the standard transfer form view. It does not create any new screens, menus, reports or scheduled jobs, and it does not change any stock or sales calculations, quantities or validations. It relies on the link that already exists between a transfer and its sales order, provided by the sale and stock integration.

In short, it is a small navigation helper: from a delivery or other transfer, one click takes you to the originating sales order.
